Question

The school glee club is collecting money for a sing-a-thon. Their goal is to collect $105. So far, they have collected x dollars each from 15 people and y dollars each from 10 people. Which expression represents how much more money the club needs to collect to reach the goal?

Answer 1

To represent the amount of money the school glee club still needs to collect, you would write $105 - (15x +10y) = m.

m stands for the amount of money that they still need to collect.

You start with the total and subtract what amount has been given to find the remaining amount.
