Question

The cost y in dollars of car rental is related to the number to the number of miles driven x and is approximated by the linear equation y=0.25x+5 use the graph go estimate to the nearest whole dollar the cost of the car rental if the number of miles driven is 27

$8
$28.25
$12
$17

Answer 1

$12

Explanation:

Currently, we are solving for the cost (y).

Since we are solving for cost (y), we need to plug in our value for the number of miles driven (x). This value is given at the end of the question as we are told that the miles driven is 27. We can plug this into the equation we are given.

y = 0.25(x) + 5

y = 0.25(27) + 5

We multiply 0.25 and 27 to start off with, to get 6.75.

y = 6.75 + 5

Add.

y = 11.75

Since we are told to round up, we round up 11.75 to the nearest dollar.

y = 12

Our final answer is $12.
