Question

Gym a has an initial fee of $50 and a monthly fee of $10. Gym B has an initial fee of $30 and a monthly fee of $15. Which system can be used to find the membership time required for each gym to cost the same

a- y=50+10x
y=30+15x

b- y=50x+10
y=30x+15

c- y=50+10
y=30+15

Answer 1

a- y=50+10x

y=30+15x

Explanation:

Since the initial fee of $50 and $30 is a single fee and will never be charged again it will remain alone. Since the $10 and $15 are a monthly charge they must be multiply by how ever many months it takes to make the equal to one another.
