Question

Angie's neighbor sells T-shirts. T-shirts usually cost $20.00. This week,

each shirt is on sale for 20% off, plus 13% tax.
Calculate the sale price of one T-shirt with tax.

Answer 1

$18.08

Explanation:

20% off = 20 x 0.8 = 16

plus tax = 16 x 1.13 = 18.08

Answer 2

$18.08

Explanation:

20% of $20.00 = 0.2 x 20 = $4

Therefore, the sale price of the t-shirt with 20% off = 20 - 4 = $16

If a sales tax of 13% is then applied, final sale price = 16 x 1.13 = $18.08
