write an equation for the linear function: The cost of renting a car is a flat$26, plus an additional 0.23 cents per mile that you drive. How far can you drive for $87?

Answer 1

y= total cost
x= number of miles

y=.23x + 26

Since they give you the total amount you can spend (y) plug that in and solve for x

87=.23x +26
87-26=.23x
61=.23x
265.22=x

Answer 2

87=.23x +26
87-26=.23x
61=.23x
265.22=x
