(24 cents) per mile.

Toyotas rent for $31 per day and $.19 (19 cents) per mile.
Write a cost equation for each rental car.
Would the equation be in the form of
y = mx + b
y = .24x + 25
y = .19x + 31

The second one looks ok to me. All of the information from the first problem didn't print.

y=.19x+31
It costs $31 to rent the car and then you have to add in the .19 per mile that you drive.

To derive the cost equation for each rental car, we need to consider the fixed cost (the cost to rent the car) and the variable cost (the cost per mile driven). Let's break it down for each car rental:

1. Toyota rental:
Fixed cost (rental cost) = $31 per day
Variable cost (cost per mile) = $0.19 (19 cents)

Therefore, the cost equation for the Toyota rental car would be:

y = 0.19x + 31

Here, "y" represents the total cost, "x" represents the number of miles driven, and the equation follows the form y = mx + b, where "m" is the coefficient of the variable term (0.19x) and "b" is the constant term (31).

As for the other rental car, you mentioned that the necessary information didn't print. Hence, we don't have enough information to derive a cost equation for it.
