Hello, welcome to OpenStudy. This is the OpenStudy Feedback section, and I think that your question would be better suited for the Mathematics section.
for reference next time.
I help you out anyway though as you are new here.
So, Part A requires to different equations, one for company A, and one for company B.
$30 per mattress, + 13 charge
So, we need a variable to represent the total cost, and a variable to represent the number of mattresses. We'll use C for cost, and m for mattress.
Company B will be very similar, with minor adjustments to the fixed costs.
Part B requires us to figure out which company will charge less for four mattresses. I can already tell you it will be company B because of the reference in Part C, but let's explain why with mathematical reasoning.
We'll plug 4 in for m because m represents the number of mattresses.
So, company B is cheaper when cleaning 4 mattresses.
Not the answer you are looking for? Search for more explanations.
Part C requires us to find the difference in price between the companies if they were to each clean 7 mattresses.
It wants to know how much is saved, so
So, $12 was saved by using company B.

OMG THANKYOU SO MUCH @OrangeMaster
My pleasure. :)
@OrangeMaster i have one more question please help ,
PartA; solve -np-80<60 for n . show work please
PartB: solve 2a -5d=30 for D.show how you got the answer
If you'd like to close this question, and open your two new questions in the mathematics section. I'd be glad to help :)
