Question

Grayson charges $35 per hour plus a $35 administration fee for tax preparation. IAn chargers $45 per hour plus a 15$ administration fee. If h represents the number of hours of tax preparation,for what number of hours does Grayson charge more than Ian

Answer 1

Explanation:

We translate Grayson's charges through the following mathematical expression : 35 h + 35 where h is the number of hours while that of Ian is 45h + 15. The number of hours where the charges are equal is 35h + 35 = 45h + 15; h = 2 hrs. Hence the number of hours minimum must be above 2 hours.
