Phil received a prize of x dollars from a poker tournament. The tournament cost him 100 dollars to enter.

Chanelle deposits $7,500 into the bank. she does not withdraw or deposit money for 6 years. she earns 6% interest during that time. what will the balance be when she is finally able to withdraw her money?

Icould really use some with this question.

Witch represents the inverse of the function f(x)=1/4x-12
