Alex bought six books priced at $8 each. He got a discount of 20% off the total cost. How much did Alex pay for the books? Write your answer up to two decimal places. Am I supposed to change 20% to 0.20 and then multiply ?
Yes, but first find the price of all 6 books.
6 * 8 = ?
48
Yes, so all 6 books cost $48, now multiply by 0.20
9.6 or 0.96 ?
9.6 is correct, now subtract that from 48
38.4
Yep, that's our answer.
$38.40 after the discount
