Question

The sweater Ingrid wants to buy is $30.

It is on sale for 33% off. If the sales tax is
7%, what is the total cost of the sweater?
Round to the nearest cent, if necessary.

Answer 1

The answer is $21.40. You first figure out what the discounted price of the sweater is (which is $20). Then you multiply 20 by 1.-7 since the tax on it is 7%. Thus your answer is $21.40

Answer 2

Sweater will be $21.51

Explanation:

cost of sweater $30.00

Sale of 33% off comes to $9.90/off ($30 × 33% = $9.90)

$30.00 - $9.90 =$20.10

Sale cost of sweater is $20.10

$20.10 × 7% sales tax = $1.41

$20.10 + $1.41 = $21.51
