Question

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

Answer 1

6 books at $ 8 = (6 * 8) = 48

if he got a discount of 20%, then he paid 80%
0.80(48) = 38.40 <== what he paid

Answer 2

Answer: The amount paid by Alex = $38.4

Explanation:

Given: The cost of each book = $8

Then the total cost of six books =
`6*8=\$48`

The discount percent on total cost = 20 %

Then, discount amount = 20% of total cost

=
`0.20*48=\$9.6`vvvvvvv

Therefore, the amount paid by Alex =
`48-9.6=\$38.4`

Hence, the amount paid by Alex = $38.4
