Question

a racquetball club charges $10 for a one- month trial membership. After the trial month, the regular membership fee is $12 per month. Write an equation that gives the total cost of membership C as a function of the length of membership , (in months)

Answer 1

The membership is $10 for the first month and $12 for each additional month.

C = 10 + 12(m-1)

C = 10 + 12m - 12

C = 12m-2
