Your clothes washer stopped working during the spin cycle and you need to get a person in to fix the washer. Company A costs $20 for the visit and $15 for every hour the person is there to fix the problem. Company B costs $40 for the visit and $5 for every hour the person is there to fix the problem. When would Company B be cheaper than Company A?
Set up the cost functions:
Set them equal to each other:
15h + 20 = 5h + 40
Using our equation solver, we get h = 2.
With h = 3 and beyond, Company B becomes cheaper than Company A.
Set up the cost functions:
- Company A: C(h) = 15h + 20
- Company B: C(h) = 5h + 40
Set them equal to each other:
15h + 20 = 5h + 40
Using our equation solver, we get h = 2.
With h = 3 and beyond, Company B becomes cheaper than Company A.
