Question

The total cost of a gym

membership is $29 per month
plus a one-time fee of $50.
Write an equation that
represents the total cost, c, in
terms of months.
If I paid $920 in gym fees, then how many months was I a member at
this gym?
Process:

Answer 1

c=29m+50

30 months

Explanation:

If you pay $29 per month, (using m as the variable), the equation would be 29m. Since there is a one-time fee of $50, we add that once. Your equation is c=29m+50. (Assuming the variable for months is m)

If you paid 920$ dollars, first we need to subtract your $50 one time fee. 920-50=870. Since you paid $29 per month, divide 870 by 29. The answer is 30. This means you were a member of the gym for 30 months.

Answer 2

y=29x+50; 30 months

Explanation:

$920-50=870

870/29=30
