Answer

Explanation:

Step1: Calculate the price of one book after discount

The discount rate is (15%=0.15). The price of one book after discount is (16\times(1 - 0.15)). [16\times(1 - 0.15)=16\times0.85 = 13.6]

Step2: Calculate the price of three books

Multiply the price of one - discounted book by 3. So the cost of three books is (13.6\times3). [13.6\times3=40.8]

Answer:

($40.80)
