Answer:
$52.80
Step-by-step explanation:
to find the sale price, we need to determine how much is 40% of $88. to do this we multiply 88 x 40%. we need 40% in decimal form, which is .40
88 x .4 = 35.2
now that we have 40% of 88, we subtract 35.2 from 88 in order to get the sale price.
88 - 35.2 = 52.8
the sale price is $52.8
