The cost of a gym membership, c, with a $50 membership fee and $22 monthly fee.?

A.Proportional
B.Non Proportional

Explanation:

x = number of months

22x = cost of using the plan for x months, ignoring the membership fee

22x+50 = cost including the membership fee

y = 22x+50 is the total cost equation. The y intercept is 50 which means the line does not go through the origin. All direct proportional equations go through the origin.

Put another way, direct proportional equations are in the form y = kx, where k is the constant of proportionality. If you didn't have the $50 membership fee, then y = 22x would be a direct proportional equation.

Answer is 0.105 ml. So yeah.
