Answer:
38.40
Step-by-step explanation:
The cost of the books before discount
6*8 = 48
Then there is a 20% discount
discount = 48*20%
48 *.20 = 9.60
Subtract this from the price
48-9.60 =38.40
The price of the books after discount
$38.40 dollars and cents
Because if she got 20% off, then she is left with that amount
