Answer:
$6.65
Explanation:
Discount = Original Price x Discount %/100
Discount = 7.5 × 20/100
Discount = 7.50 x 0.20
You save = $1.50
Original Price - Discount
7.50 - 1.50=
$6.00
You still have to add the tax:
5.75 = 0.0575
0.0575 x 7.50=
$0.65
Add $0.65 to your discount and you get the answer
$6.65
