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?

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.

1. isolate the variable, in this case, d. subtract 35.5 on both sides of the equation.2. 52 subtracted by 35.5 is 16.53. therefore your answer would be d= 16.5this is the basics of pre algebra, isolating variable through adding, subtracting, multiplying, and dividing, if you have any other questions to ask just comment!
