Question

The cost of renting a car is $55/wk plus $0.15/mi traveled during that week. An equation to represent the cost would be

y = 55 + 0.15x,
where x is the number of miles traveled.

What is your cost in dollars if you travel 50 mi?

Answer 1

$62.50

Explanation:

We have been given an equation
`y=55+0.15x`, which represents cost of renting a car and x is the number of miles traveled.

To find the cost of renting a car to travel 50 miles, we will substitute
`x=50` in our given equation as:

`y=55+0.15(50)`

`y=55+7.50`

`y=62.50`

Therefore, the cost of renting the car to travel for 50 miles would be $62.50.

Answer 2

$62.50

Explanation:

We have been given the equation that models the cost of renting a car, y, as a function of the number of miles traveled, x;

y = 55 + 0.15x

If an individual travels 50 mi during a given week, the cost in dollars is determined by substituting x with 50 in the cost function above;

y = 55 + 0.15(50)

y = 62.5
