2. Jose is comparing the prices of two carpet cleaning companies. Company A charges $0.40 per square foot of carpet area and an additional $22 per day for services. Company B charges $0.60 per square foot of carpet area and an additional $18 per day for services.
Part A: Write equations to represent Company A and Company Bs total charges for cleaning a certain carpet area in a day. Define the variable used in the equations:
Part B: Which company would charge less for cleaning 500 square feet of carpet area? Justify your answer.
Part C: How much money is saved by using the services of Company A instead of Company B for cleaning 200 square feet of carpet area?

Answer 1

PART A :
f stands for # of sq ft

company A :
0.40f + 22 = total charges per day

company B :
0.60f + 18 = total charges per day

PART B :
company A : .40(500) + 22 = 200 + 22 = 222 for 500 sq ft.
company B : .60(500) + 18 = 300 + 18 = 318 for 500 sq ft
company A charges less

PART C :
company A : .40(200) + 22 = 80 + 22 = 102 for 200 sq ft
company B : .60(200) + 18 = 120 + 18 = 138 for 200 sq ft
Money saved b y using company A : 138 - 102 = 36
