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: The amount paid by Alex = $38.4

Step-by-step explanation:

Given: The cost of each book = $8

Then the total cost of six books = [tex]6\times8=\$48[/tex]

The discount percent on total cost = 20 %

Then,  discount amount = 20% of total cost

=[tex]0.20\times48=\$9.6[/tex]vvvvvvv

Therefore, the amount paid by Alex = [tex]48-9.6=\$38.4[/tex]

Hence, the amount paid by Alex = $38.4
