Question

Determine when the cost of the two services will be the same amount, and what the price will be. One cable television provider has a $50 setup fee and charges $50 per month, and another cable provider has a $130 equipment fee and charges $40 per month. A subscriber would have paid either company $ for months of service.

Answer 1

50+50m=130+40m subtract 40m and 50 from both sides

10m=80 divide both sides by 10

m=8 so at 8 months both plans cost the same...

That cost is 50+50(8)=$450
