<span>you have to create variables that have the same coefficient</span>
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

Answer:
This would be 6 x 10 -4
The function would look like: (4x)+160 where x is the mph over the speed limit
So if you Input 8 it would be (4*8)=160, which would be: $192
