Answer:
$35.7
Step-by-step explanation:
you can convert 15% to a decimal by dividing by 100.
15/100 = .15
if you multiply the decimal by the cost of the shirt you get how much the discount is.
0.15 * $42 = 6.30
so a 15% discount on a $42 shirt is $6.30 off. So you subtract the discount from the total cost.
$42 - $6.30 = $35.70 that is the sale price of the shirt.
