I'll admit, I thought the answer was 25, at first, as the fries in the second equation are easy to not notice (there's four of them, not two).
Due to this, I assume the second equation is supposed to be "burger fries fries fries fries = 9" (b c c c c = 9) rather than "burger fries fries fries fries = 9" (b cc cc = 9, or b c * c c * c). And the reason I assume that is because without multiplication in the second equation, the answer is simple. With multiplication, the answer is "a=√2 or a=−√2." In algebra, which this is using, two variables (letters, like a or b, rather than numbers) put next to one another indicates multiplication of the two variables. So to some, this may be confusing as the second equation seems to suggest you multiply twice. But if you attempt to multiply, it soon gets very complicated. So I assume that the creator of the image just wanted to keep things nice and short like the first and last equation, so they squeezed the longer equation (consisting of 5 variables, rather than 3 like the other two equations) into the same length as the first and second equation.
Another confusing aspect is "why did the image creator use food products instead of letters for their algebraic expression? This must have some sort of real-world application, right? Otherwise they just could have used a, b and c, for drinks, burger, and fries." Well, in the real world, when you purchase things, you don't multiply them together, you add them. So I think a lot of people naturally assume there is no multiplication in this expression, and thus, accidentally overlook the fact that there's multiplication in the last expression. Like, if you get $1 fries and a $10 soda, it would typically cost $11, but in this equation they multiply them, effectively getting the fries for free since anything multiplied by 1 is whatever the 1 multiplied.. re-state://background_color_rgba (0, 0, 0, 0), font_color_rgb (77, 77, 77), justifyLeft
Wow. I also just noticed that G@G also removed the plus signs from my example equations. I'm sure that'll cause some confusion. Man, G@G has some real wonky code.
@DaveToo The division is implied since you need a total of 4 to be divided by 4 objects over which the 4 counting units are distributed. If the total was 6 and there were 4 objects, the answer would be 1.5, etc.
Coke+Coke+Coke =30 (that means a coke is worth 10) 10+Hamburger+Hamburger=20 (means that a hamburger is worth 5) 5+Fries(2x)+Fries(2x)=9 (means Fries are worth 1) 5 + 1 x 10=? This is the point you must remember PEMDAS which is an acronym for the order in which you must do calculations if multiple symbols are involved. PEMDAS stands for Parentheses, Exponents, Multiplication, Division, Addition, and then Subtraction. In this case, going in order, multiplication comes first and then addition, so....
I'm so dumb cuz I wasn't paying full attention to the information provided to properly answer the problem. I know it's too late to change my answer, but I realize now my mistake. Guess I'll be enrolled in the summer break remedial algebra class. 😒
Ah I see there are 4 fries in the 3rd one lol Anyways Pepsi is still the same so 10 Burger too so it's 5 Now fries: Burger + 4 fries = 9 4 fries = 9 - 5 (which is the Burger) 4 fries = 4
Ha! so I did admittedly cheat but I was so wrong… haha! I was like 70! And then I saw that you told someone else that that was wrong so I looked for other answers and realized the fry thing but that pout me at 60 and it still want working. And then I saw someone mention the order of operations and I dropped my jaw. Like… I bet that that is why I am always getting these stupid things wrong. And now 15 does make sense…
The cokes are 10 each, which is why they add to 30. The two burgers must equal 5, because otherwise with the coke they would not add up to 20. In order to get 9 with the burger, which equals 5, the chips must have a value of 2. Burger, plus chips, plus coke = 17.
@ChubbyKing Oh damn, it was so easy to mess that up. Well, two times 10 plus 5 is 25 (order of operations - multiplication comes before addition in any equation). Hopefully I got it right this time :)
You know, this is not worth it, but you certainly got me. 1 pack of fries = 1, times 10, + 5 = 15. Next you will have me counting sesame seeds and ice cubes. You win.
It was already too late for all of this, but now I realize after being up this late that my brain is aging, so thank you for that. So many details, to skip over. That was a good one though, I will check back for more content. Maybe less mistakes on my part, any way good day madam!
I got faked out like that too. Look closely line # 3 has 4 fries. and line # 4 is 5+(1 X 10) =15 due to the order of operations... I was totally fooled.
Are you going by your own calculations or is there an honest answer to this by the creator of this mathematic exercise? Because it's very obvious it's 60. lol
- First section: the glasses of pop/soda have a value of 10 (10 + 10 + 10 = 30).
- Second section: the glass of pop/soda has a value of 10 and the burgers have a value of 5 (10 + 5 + 5 = 20).
- Third section: the burger has a value of 5 and the fries have a value of 1 per bag. There are four bags in total (2 + 2) for a total of 9 (5 + 2 + 2 = 9).
Fourth section: the burger has a value of 5 and the single bag of fries has a value of 1. This is then multiplied by the value of the glass of pop/soda (a value of 10), which is 5 + 1 (= 6) x 10 = 60. lol
Again, if you add up all the totals from each section (30 + 20 + 9 + 60) it equals 119. Please explain how is this wrong? lol
Oh, FFS. Are you kidding me? Reading below, it's obvious you've "liked" every answer that came to a total of 15. However, a conclusion to that total ONLY works if there's a bracket around the values of the fries and pop/soda in the last section! lol i. e. 5 + [1 X 10 = 10] = 15. But there were no brackets! Had there have been brackets in your example, I easily would have come to a total of 15. But given there were no brackets, that total is is not only flawed, it is incorrect. The ONLY way to come to a total of 15 is if the value of the fries and pop/soda are subtotalled within brackets and then added to the burger's value of 5. lol I know that may sound like a "technicality" or me being a stickler, but bracketing and punctuation within mathematics is a thing, and is important because it changes the outcome of the equation. Even if you grab a calculator and add the value of the burger to the value of the fries and multiply with the value of the pop/soda straight across it comes to 60. Again, the ONLY way to come to a total of 15 is to bracket the values of the bag of fries and glass of pop/soda as a separate subtotal. Those brackets are not present, so why would it be tallied that way? My answer of 60 still stands. lol If you want to come to a total of 15 without brackets it doesn't work.
Nope. Pedmas applies always. If there was brackets they would go first no matter what it was +-÷×. Since there is no brackets the order is ÷ × + - it's pretty basic stuff.
shit, so there is. okay now I get it. Very well done. I was totally faked out. When i develop an exam for my next class I am going to get you to help me.
A coke is ten, since three of them = 30 A hamburger is five, since two them and a coke = 20 French Fries are two since one burger and two fries = 9 Therefore one burger, (5), one fries, (2) = 7, multiplied by one soda, (10), = 70 No part of that last set equates to 15.
