Step-by-step explanation:
Set up a proportion.
3/25 = x / 20 Notice that both times are in the denominators. Be sure you always set up a proportion that way. Like units in the denominator. Like units in the numerator.
Cross multiply
3 * 20 = 25 * x Combine
60 = 25x Divide by 25
60/25 = x

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
