How do you calculate sales tax?

I'm trying to stay on a budget for the first time since I got my first job and I don't want to spend more than $25 on my next trip to Walmart. So I want to calculate every penny before I walk into the store.

I got my list and the exact prices of my items. My problem is calculating my final price with the sales tax.
My first question is do they tax the non-food items separately? For example (I'll use my previous receipt):

Non-Food Items
Lotion ($3.97) + Lotion ($3.97) + Stylus Pen (.94) + Earphones (7.00)= $15.88 + (.0825 × 15.88= 1.31) $1.31= $17.19
Food
Honey ($2.98) + Spinach ($2.46) + Gum ($2.24)= $7.68
Total: $7.68 + $17.19= $24.87

But here's where I get really confused... they taxed me.84 cents, 8.250% of my subtotal which was $23.56, (what is says on receipt) making my total $24.40!!! Where did the.84 cents come from?

  • I'm confused about what you are doing. Are you showing two different sales? Like the list of food and non-food items different than the last paragraph?

    If those are two different things, maybe the "subtotal" is your total purchase of both taxable and non-taxable.
    Taxable purchase = 10.18
    Non-Taxable = 13.38
    Total purchased: 23.56
    Tax on 10.18 = 10.18 * 0.0825 = 0.84
    Total with Tax = 24.40

  • total * (1 + percentageInDecimalForm)

    10 percent in cali so. 8.99 * 1.10 = 9.88
