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 equations to represent company a's and company b's total charges for cleaning a certain number of windows. define the variable used in the equations. (4 points) part b: which company would charge less for cleaning 8 windows? justify your answer. (3 points) part c: how much money is saved by using the services of company b instead of company a to clean 6 windows? (3 points) (10 points)

Part A:

Let 'x' be the number of windows cleaned.

Let 'y' be the total cost of cleaning 'x' windows.

Company A charges $6 per window and an additional $12 as service charges. So equation becomes

Company B charges $5 per window and an additional $15 as service charges. So equation becomes

Part B :

Cost for cleaning 8 windows.

Company A = =$60

Company B = =$55

Company B charges less for 8 windows.

Part C:

Cost for cleaning 6 windows.

Company A = =$48

Company B = =$45

Money saved by using company B is dollars.

the anwser is d) 75°

step-by-step explanation:

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x
