Andy bought 4 novels. The original price of each novel was $44. He was given 20% discount on the first novel and 25% discount on the rest of the novels. How much did he pay for the 4 novels altogether?
Cost of the first novel after 20% discount in percent
= 100% - 20%
= 80%

Cost of the first novel after discount
= 80% x 44
= ⁸⁰₁₀₀ x 44
= $35.20

Number of the rest of the novels that enjoyed 25% discount
= 4 - 1
= 3

Cost of each of the rest of the 3 novels after 25% discount in percent
= 100% - 25%
= 75%

Cost of each of the rest of the 3 novels
= 75% x 44
= ⁷⁵₁₀₀ x 44
= $33

Cost of the rest of the 3 novels that enjoyed 25% discount
= 3 x 33 
= $99

Total cost for the 4 novels
= 35.20 + 99
= $134.20

Answer(s): $134.20
