Answer:
c = 40 + 50m
Step-by-step 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.
