arlene is comparing the prices of two truck rental companies. company a charges $7 per hour and an additional $30 as service charges. company b charges $8 per hour and an additional $40 as service charges.

part a: write an equation to represent each company's total charges for renting a truck for a certain number of hours. for both equations (one for company a and one for company b), define the variable used. (4 points)

part b: which company would charge less for renting a truck for 8 hours? justify your answer. (3 points)

part c: how much money is saved by using the services of company a instead of company b to rent a truck for 2 hours? (3 points)

The answer to part A is, Company A's equation is, 7x+30. Company B's equation is 8x+40. The variable x is used to represent the number of hours you drive in each truck.

The answer to part B is, Company A will charge less for renting a truck for 8 hours because you need to substitute the x in each equation for the number 8, and doing this to both equations, then solving them, will result in you paying less to ride with Company A.

work for part b: Company A: 7 (8) + 30 Company B: 8 (8) + 40

The answer for part C is, you will save $12 renting a truck from Company A apart from Company B.

work for part c: Company A: 7 (2) + 30= 44 Company B: 8 (2) + 40= 56

Hope this helps!
