Answer:
$22.47
Explanation:
Shirts are on sale for 30% discount
The original price of one shirt is $15
Discount = percentage discount/100 × original price =
× $15 = $4.5
The selling price of one shirt is therefore;
$15 - $4.5 = $10.5
For two shirts, the selling price is 2 × $10.5 = $21
Tax = Percentage tax/100 × selling price =
× $21 = $1.47
The total cost of these two shirts at sale price = $21 + $1.47 = $22.47
