Me in this question i need it by latest tomorrow !
down below is my !
company 1 says that they will complete the job for $12 per foot of fencing. company 2 says that they will charge you $4500 for the first 500 feet of fencing and $25 for each additional foot. determine the cost of fencing for both companies .remember that both companies need to charge 6.35% sales tax. show work

So Company 1 charges $6,000 dollars for 500 feet of fence.
Company 2 only charges $4500/500 or $9.00/foot up to 500 feet.

The difference of 6,000 - 4500 = $1,500 so using Company two you will get 60 more feet of fence then both companies break even. After 500 ft
Company 1 only charges $12.00 dollars a foot and Company 2 charges $25.00 a foot.

So if you need 500 ft Company 1 costs 6,000 + 391.80 tax
Company 2 costs 4,500 +293.85 tax
Question does not ask how many feet is going to be needed?

Did u want to find the value of x?
