Answer:
The amount of money left can be represented by expression n-75
In an equation, N represents a specific number, not any number. N + 9 = 12 means N is a number which, when added to 9, must give the answer 12. So N can only be the number 3 because only 3 + 9 is equal to 12.
N = 12
•So N-75 = 12+75 =>"87"<
