lynn needs a truck to move some evidence out of her back yard before investigators arrive. She finds the cost C, of renting a truck is $25 per day plus $1 per mile, m. Write an equation for the cost in terms of miles driven.

Wouldn't that just be

C = m + 25 , where m is the number of miles.

y=m=25

To write an equation for the cost in terms of miles driven, we can consider the two components of the cost: the fixed cost per day and the variable cost per mile.

Let's break down the equation step-by-step:

The fixed cost per day is $25. This means that no matter how many miles Lynn drives, she will have to pay $25 as the base cost for renting the truck.

The variable cost per mile is $1. This means that for every mile Lynn drives, she will have to pay an additional $1.

To combine these two components into an equation, we can use the following formula:

Cost = Fixed cost per day + (Variable cost per mile) * Miles driven

In this case, the fixed cost per day is $25, and the variable cost per mile is $1. Thus, the equation for the cost in terms of miles driven can be written as:

Cost = $25 + $1 * Miles driven

Simplifying this equation further, we have:

Cost = $25 + $1 * M

Therefore, the equation for the cost in terms of miles driven would be:

C = 25 + M

where C represents the cost and M represents the miles driven.
