Question

A shopper bought a watermelon,a pack of napkins,and some paper plates. In his state, there is no tax on food. The tax rate on non-food items is 15 percent. The total for the three items he bought was $8.25 before tax, and he paid $0.19 in tax. How much did the watermelon cost?

Answer 1

Explanation:

the question is about 15% tax equaling 19 cents. So what amount of principle would be needed to make 19 cents worth of tax.

.19/.15=1.26666666

round up to $1.27 since we don't have parts of pennies for money.

8.25-1.27=$6.97 for the watermelon.
