Question

A racquetball club charges $10 for a one-month trial membership. After the trail month, the regular membership fee is $12 per month.

A. Write an equation that gives the total cost of a membership (C) as a function of the length of membership (m) in months. Explain how you got that answer.

B. Find the cost of the membership after 8 months.

Answer 1

membership is discounted $2 for first month
c=cost of one month
d=discount=$2
x=# of months
xc - 2= total cost
x for 1 month is 1, c is always 12, -2 is constant
1 x(12) - 2=10 for first month
8 months
8c -2=total cost for 8 months
8 x 12 - 2= 94 for 8 months
