Question

You purchase a t-shirt for $9.55 and a pair of jeans for 18.12 from Old Army at 7% sales tax.

How much change should you receive if you give the cashier two twenty-dollar bills?

Answer 1

$10.39 is the change

Explanation:

We start by calculating the total score

9.55 + 18.12 = 27.67

we now calculate the sales tax

This is 7% of the total

= 7% of 27.67

7/100 * 27.67

= $1.94

The total now comes;

1.94 + 27.67 = $29.61

The total was 2 * 20 = $40

The change was;

$40 - $29.61 = $10.39
