Navin signed up for a gym membership. The cost was $125 plus $20 each
Lisa [10]

Answer:

a) the initial value is $125, and it represents the cost Navin has to pay in the beginning

b) the rate of change is  $20 per month, and it represents the cost he has to pay per month

c) linear; the equation for it is y = 20x + 125

d) The rate of change is constant because each month, Navin always has to pay $20.

e) This is <u>partial variation</u> because the equation y = 20x + 125 doesn't follow y = kx

Have a lovely rest of your day/night, and good luck with your assignments! ♡
