part B: which company would charge less for 5 seconds of laundry ?

part C: how much money is saved by using the services of company A instead of company B to clean 9 loads of laundry

Answer 1

If you meant loads instead of seconds then this is what you get:

Part A:
    A(x)= 20x+8
    B(x)= 24x+4

Part B:
    Company A. It cost $108 for 5 loads, while it cost $124 for 5 loads using company B

Part C:
   For 9 loads, you save $32 when using company A vs company B.
