A truck rental company rents n moving truck for one day by c

A truck rental company rents n moving truck for one day by charging $39 plus $0 10 per mile. Write a linear equation that rotates the cost C, in dollars, of renting the truck to the number x of miles driven What is the cost of renting the truck if the truck is driven 180 miles? 482 miles? Type the linear equation that relates the cost C, in dollars, of renting the truck to the number of x miles driven (Use integers or decimals for any numbers in the expression. Do not include the $ symbol in your answer.)

Solution

The cost of running x miles @ $0.10 per mile = $ 0.1 x

Adding the fixed charge (of $39) for a day the cost C = $ (39 + 0.1 x)

The cost of renting the truck when it is driven for 180 miles

= 39 + 180 x 0.1 = 39 + 18 = $ 57

The cost of renting the truck when it is driven for 482 miles

= 39 + 482 x 0.1 = 39 + 48.2 = $ 87.2

The linear equation for cost of renting the truck

C = 39 + 0.1 x
