Calculate remaining balance on allowance

Need some help with a formula question I've been dying to solve but haven't found a solution to it.

' Calculate the amount left from his allowance in Cell G15 if the student gets $100 per week. Display this with the label Allowance remaining in cell A15, text wrapped.'

The wording of the question and the fact that the file is called Exercise 1 suggests that this is some sort of homework assignment. We do not do your homework for you. If you have made progress and have a specific question about an Excel feature that is giving you trouble, we are happy to help. But please do not post your assignment and ask us to complete it for you.

Clearly the remaining balance is $100 minus the total of expenditures. You already have the total of expenditures in the file, so it seems you just need to modify the formula in G15 accordingly. Can you narrow it down to specifically what is the part giving you trouble?
