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.
