A rental car agency charges x dollars per day plus y dollars per mile to rent any of the mid-sized cars at the agency. The total costs for two customers are shown below.

Jackson  3 150 217.50
Bree 2 112 148.00

How much will it cost to rent a mid-sized car for 5 days and drive 250 miles? Explain.

Set up your chart as 2 simultaneous equations as follows:

 

3x + 150y = 217.50
2x + 112y =148, solve for x, y

x = $60 - charge per day

y =$0.25 - charge per mile

So, now that we know the daily charge and cost per mile, we can easily figure out the cost of renting a mid-sized car for 5 days and drive 250 miles as follows:

5x + 250y =

(5*$60) + (250 *$0.25) =

$300     +    $62.50

=$362.50 - Cost of renting a car for 5 days and drive 250 miles.
