I think the answer is 15.
Drinks are $10, burgers are $5, and fries are $1
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

This is the answer:
EQUATION 1: COKE + COKE + COKE = 30
So, 3 * COKE = 30.
So, COKE = 30 / 3.
So, COKE = 10.
EQUATION 2: COKE + BURGER + BURGER = 20
So, COKE + 2 * BURGER = 20.
But, COKE = 10.
So, 10 + 2 * BURGER = 20
So, 2 * BURGER = 20 - 10 = 10
So, BURGER = 10 / 2 = 5.
EQUATION 3: BURGER + 2 * FRIES + 2 * FRIES = 9
So, BURGER + (2+2) * FRIES = 9
So, BURGER + 4 * FRIES = 9
But, BURGER = 5.
So, 5 + 4 * FRIES = 9
So, 4 * FRIES = 9 - 5 = 4
So, FRIES = 4 / 4 = 1.
EQUATION 4: BURGER + FRIES * COKE = ?
But, BURGER = 5.
And, FRIES = 1.
And, COKE = 10.
So, 5 + 1 * 10 = ?
So, 5 + 10 = ?
So, 15 = ?
So, the answer is 15.
QED (Quod erat demonstratum)
- a
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....
1 x 10=10 + 5= 15
Use BODMAS rule. Solve for "?".
Soda Soda Soda = 30
Soda Burger Burger = 20
Burger Fry Fry = 9
Burger Fry x Soda = ?
Soda = 10
Burger = 5
Fry = 2
Burger Fry * Soda = ?

Burger (Fry * Soda) = ?
Burger (2 * 10) = ?
Burger (20) = ?
5 (20) = ?
5 20 = 25

Lol this is has a good amount of replies. Okay let's start:
3 (pepsi) = 30
Pepsi = 30/3
Pepsi = 10
Pepsi 2burgers = 20
We know Pepsi is 10
10 2burgers = 20
2 burgers = 20 - 10
2 burgers = 10
Burger = 10/2
Burger = 5
Burger 2 fries = 9
We know Burger is 5
5 2 fries = 9
2 fries = 9 - 5
2 fries = 4
Fries = 4/2
Fries = 2
We have them all
Pepsi =10, Burger = 5, fries = 2
Now
Burger fries × Pepsi
5 (2 × 10)
We do the ones in the parenthesis first
5 20
= 25 Final answercokes=x=10
burgers=y=5
fries=z=2
1. 3 cokes = 3x=30 x=10
2. 1 coke or 1x + 2 burgers or 2y
x+2y=20 or 10+2y=20 = 2y=10 y=5
3. (1 burger=y=5) + (2 fries=2z) = 9
5+2z=9 = 2z=4 = z=2
4. Burger + Fries x Coke = ?
(y+z) x =
(5+2)10 =
7x10= 70Ha! 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…
yeah. the answer is: if you challenge peoples intelligence, it's really easy to motivate them to commit to utterly pointless tasks xD
Seventeen aka 17. And this really only shows how terrible soda is >.< Despite this I also want a burger now though, and fries.
Each glass of cola has a value of 10.
Each burger has a value of 5.
Each french fries has a value of 1.
The answer is 16.Its 17.
Cups are 10, burger is 5 and fries are 215.
Coke is 10
Burger is 5
One Bag of fries is 1
5 1×10= 15 (multiplication first)
5 10=15It's 17. Skip the coke. sugar is bad. So is fat and salt but at least there's macronutriants.

...16The answer is 17. A prime number. I like primes! :)
15 , using typical order of operators.
A. Pop = 10 each.
B. Pop =10. 2 burgers = 10, so 1 burger = 5.
C. 9 - 5 = 4. Fries = 1 each.
D. 5 + ( 1 x 10 ) = 5 + (10) = 15.So we can safely assume that the burger can't be anything over 9.5 due to the fact that 1 2 chips is 9 but I'd say:
Coke:10
Burger: 5
Chips: 225. Soft drink equals 10, burger equals 5, fries equal 2.

Soda = 10
Burger = 5
Fries = 2
5+2×10

>>2517, like who knows countless others. Did I get diabetes?
15 right? Those double vs single fry bags are sneaky tho
In-N-Out Burger is my favorite Burger or fast food joint, but I believe they are mostly based on the west coast of the US
15
Burger is 5, fries are 1, cola is 10
5 1*10=5 10=15 (there are no parentheses, so we should multiply first)Burger is 5. Fries are 2. Drink is 10. 5+2 is 7x 10 is 70
