Question

Colton's Gym charges an initiation fee of

$40 plus a monthly fee of $50. Which
of the equations below shows the cost
c of joining the gym for m months?
O c = 50 + 40m
O c = 40 + 50m
C + 40 - 50m

Answer 1

c = 40 + 50m

Explanation:

40 is a constant, it is not affected by the number of months the person works out at the gym for.

There is a monthly fee of $50. So, every month Colton gets charged $50, so this is the variable.

The total cost would be represented by the equation c = 40 + 50m then.

Let's look at this using a number for m.

If Colton went to the gym for 2 months then we can set up the equation like this:

c = 40 + 50(2)

c = 40 + 100

c = 140

Therefore he spends a total of $140 for 2 months.

Hope this helps!
