Jenson bought 4 magazines. The original price of each magazine was $30. He was given 5% discount on the first magazine and 30% discount on the rest of the magazines. How much did he pay for the 4 magazines altogether?
Cost of the first magazine after 5% discount in percent
= 100% - 5%
= 95%

Cost of the first magazine after discount
= 95% x 30
= ⁹⁵₁₀₀ x 30
= $28.50

Number of the rest of the magazines that enjoyed 30% discount
= 4 - 1
= 3

Cost of each of the rest of the 3 magazines after 30% discount in percent
= 100% - 30%
= 70%

Cost of each of the rest of the 3 magazines
= 70% x 30
= ⁷⁰₁₀₀ x 30
= $21

Cost of the rest of the 3 magazines that enjoyed 30% discount
= 3 x 21 
= $63

Total cost for the 4 magazines
= 28.50 + 63
= $91.50

Answer(s): $91.50
