Answer:
When the number of sessions is equal to 10, the total cost is the same in the two plans
Step-by-step explanation:
Let
y ---> the total cost
x ---> the number of sessions
we know that
The linear equation in slope intercept form is equal to

where
m is the slope
b is the y-intercept
Planet Fitness
we have
The slope is equal to

The y-intercept or initial value is equal to

substitute
----> equation A
Gold's Gym
we have
The slope is equal to

The y-intercept or initial value is equal to

substitute
----> equation B
Equate equation A and equation B

solve for x

therefore
When the number of sessions is equal to 10, the total cost is the same in the two plans
