Answer:
In 4 months the cost of both gyms will be the same.
Step-by-step explanation:
At first we need to model the function to calculate the cost of the 2 gyms.
Slope-intercept equation of linear function

where
 slope of line
 slope of line
 y-intercept
 y-intercept
Let linear function to calculate total cost of gym be:

where
 total cost of gym
 total cost of gym
 cost per month (slope)
 cost per month (slope)
 number of months
 number of months
 start-up fee (y-intercept)
 start-up fee (y-intercept)
For Gym 1
 ,
  ,  
 

For Gym 2
 ,
  ,  
 

In order to find the number of months the cost of both gyms will be the same, we need to equate both functions and solve for number of months 


So,
In 4 months the cost of both gyms will be the same.
