Question

A boy bought four roti and five patties for $317.50. If he had bought five roti and three patties, then he would have paid $340.00.
Write two equations in terms of r and p to represent the information.

Answer 1

Answer:

Step-by-step explanation:

Let the number of rotis and patties be r and p respectively.

Given, four rotis and five patties can be bought for $317.50.

And, five roti and three patties can be bought for $340.00.

Hence, 4r + 5p = $ 317.50

            5r + 3p = $ 340
