Jake is comparing the prices of two laundry service companies. company a charges $20 per load and an additional $8 as service charges. company b charges $24 per load and an additional $4 as service charges.
part a: write equations to represent company a's and company b's total laundry charges for a certain number of loads. define the variable used in the equations.
part b: which company would charge less for 5 loads of laundry? justify your answer.
part c: how much money is saved by using the services of company a instead of company b to clean 9 loads of laundry?

Part A : 20x + 8 and 24x + 4

Part B : Company A charges less and compared to company B.

Part C : Using the services of company A saving is $32

Step-by-step explanation:

Jake is comparing the prices of two laundry service companies.

Part A:

Company A charges $20 per load and an additional $8 as service charges.

So the expression that represents the charges = 20x + 8

Similarly for company B the expression will be charges = 24x + 4

Here x represents the number of loads of the laundry.

Part B:

In this part we have to compare the charges for 5 loads of the laundry.

Charges of company A : 20x + 8 = 20×5 + 8 = $108

Charges of company B : 24x + 4 = 24×5 + 4 = $124

Therefore, company A charges less.

Part C :

Company A charges for 9 loads = 20×9 + 8 = $188

and company B charges for 9 loads = 24×9 + 4 = $220

Saving by using the services of company A instead of company B

= 220 - 188

= $32
