How to solve a problem by collecting like terms?

Let C represent the entrance fee for a child and A represents the entrance fee for an adult, we therefore have:

C = RM(3x-y)

A = RM(3x-y) + RM2y = RM3x – RMy + RM2y = RM(3x – y + 2y) = RM(3x + y)

Since Mr. Kamal and his wife bring their three children to the circus, this implies that we have 2 adults and 3 children.

The amount he should pay altogether (T) can therefore be calculated by collecting the like terms as follows:

T = 3C + 2A = 3RM(3x – y) + 2RM(3x + y)

T = RM9x – 3y + RM6x + 2y

T = RM9x + RM6x – 3y + 2y

T = RM15x – y
