maria is comparing the prices of two window cleaning companies. company a charges $6 per window and an additional $12 as service charges. company b charges $5 per window and an additional $15 as service charges.

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

part b: which company would charge less for cleaning 8 windows? justify your answer.

part c: how much money is saved by using the services of company b instead of company a to clean 6 windows?

Step-by-step explanation:

Part A: Company A charges $6 for a window and $12 for a service clean. If you add that up it would be 6 + 12 =18 so company A would be making $18 per customer. Company B charges $15 + $5 for a whole cleaning which would make them $20 per customer. That is better then $18 so business B would be making more money.

Part B: For cleaning 8 windows company B would charge less because 8 x 5 = $40 for all the windows and company A would be charging $6 for a window which is more so 8 x 6 = 48. Company B charges less.

Part C: Company B charges 5 dollars for thier services on windows as Company A charges 6. You would be saving a dollar by buying at company B.
