Austin is comparing the prices of two car rental companies. Company A charges $24 per day and an additional $25 as service charges. Company B charges $22 per day and an additional $40 as service charges.

Part A: Write an equation to represent each company's total charges for renting a car for a certain number of days. For both equations (one for Company A and one for Company B), define the variable used.

Part B: Which company would charge less for renting a car for 4 days? Justify your answer.

Part C: How much money is saved by using the services of Company A instead of Company B to rent a car for 6 days?

I'm really sorry if you don't get a response to your question today, it is a Sunday so not a lot of people can respond right away. I hope you stay though :p

its fine

dude · Answer

For part A you want to write two equations, one for A and one for B

For Company A they told you that the rate is 24/day + 25 for additional
For Company B they told you that the rate is 22/day + 40 for additional

The equations should be in linear form 
$y=mx+b$
m is the rate
b is the extra in this case

dude · Answer

For part B you want to compare both values

Substitute 4 into each equation and solve for y. You can then compare the results

dude · Answer

For part C do the same as part B, only substitute 6 in for x and solve for y

Once you solve it subtract A and B to compare the values
