Answer
Explanation:
Step1: Calculate the price after 20% off
The discount amount for the 20% - off sale is $32.99\times0.20 = 6.598\approx6.60$. The price of the book after the 20% - off sale is $32.99 - 6.60=26.39$.
Step2: Calculate the discount from the 15% - off coupon
The discount amount from the 15% - off coupon is $26.39\times0.15 = 3.9585\approx3.96$.
Step3: Calculate the total savings
The total savings is the sum of the two - step discounts, which is $6.60 + 3.96=10.56$.
Answer:
A. $10.56$
