Question

The relationship between the yearly fee that the local YMCA charges and the fee to bring a friend is modeled by the linear function f (x) = 5x + 795, where x is the number of friends you bring with you each year. If the total fee is $855 one year, how many friends did you bring to the YMCA that year?

Answer 1

12 friends

Explanation:

Fill in the given number and solve for x.

855 = 5x +795 . . . . . the total fee was 855

60 = 5x . . . . . . . . . . . subtract 795

12 = x . . . . . . . . . . . . . divide by 5

The number of friends you brought was 12.
