Answer: 6 months
Step-by-step explanation:
variable will be how many months kiri has joined the gym
equation in form y = mx + b
y = 25x +45
b is the constant and y intercept
I solved this by subtracting $45 from the total $195 because it is the starting payment. I then got $150. After that we divide $150 by 20 so we know how many months he has had a membership for. Finally, we get 6 months he has had a membership.
Hope this helped!!!
