Answer

Explanation:

Step1: Calculate the total cost before discount

The cost of one book is $8, and Alex bought 6 books. So the total cost before discount is $8\times6 = 48$.

Step2: Calculate the discount amount

The discount rate is 20% or 0.2 in decimal form. The discount amount is $48\times0.2=9.6$.

Step3: Calculate the amount Alex paid

The amount Alex paid is the total cost before discount minus the discount amount, which is $48 - 9.6=38.4$.

Answer:

38.40
