Thread: Application Problem

Applications A rental company charges $29 to rent a car for one day, plus $2 for every 100 miles (or portion of 100 miles) that it is driven. Graph the ordered pairs (m, c), where m represents the miles driven and c represents the cost. (Do this graph on paper. Your instructor may ask you to turn this in.) Find the cost if the car is driven 325 miles.

My answer I got was 35.50...what am I doing wrong...completly stumped!

You are correct with your answer.

The information tells me that you have a straight line relationship between c and m of the form:

c = 2m/100 + 29

(I'm assuming we only let m be exact multiples of 100 to keep it simple)

The cost for 325 miles is $35.5 as you state.

Just thought you would like to know smacc the application problem is actually 37.00 because they charge you the extra $2 for the 25 miles... Thanks for your help...greatly appreciated!
