Value rent-a-car rental a luxury car at a daily rate of $43.09 plus 4 cents per mile. a business person is allotted $100 for car rental each day. how many miles can the business person travel on the $100

To calculate the total miles he is allowed we must setup an expression for total cost of the car per day. Cost = 43.09 +.04x where x is the number of miles driven. To find out the number of miles driven with $100, we plug in $100 for cost and solve for x. Doing this we get 100 = 43.09 +.04x, where. 04x = 56.91 and solving for x we get x=1422.75 or 1422 miles. In this case we do not round up since adding an additional mile would put us over the $100 budget. Answer = 1422 miles.
