Samuel buys 1.5 kg of apples in shop A.

Question

Samuel buys 1.5 kg of apples in shop A. The full price of the apples is 18kr/kg. Samuel gets a 15% discount on the price. Polly buys 1.5 kg of apples in shop B and gets a 10% discount on the price. What price per kilo must it be in shop B for Polly to pay as much as Samuel did in shop A?

Answer 1

Sam pays 1.5 * 18 * .85 = 22.95 Kr.

Lets say Polly needs X kg/kr to pay as much as Samuel. X * 1.5 * 0.9 = 22.95

Solve this equation and you get X = 17kr/kg
