Camilla is helping her parents choose a company to install a fence in their yard. The first company she contacts charges $20 per foot of fence, plus a $210 installation fee. The second company charges $27.50 per foot of fence, with no installation fee.
How long would the fence need to be so that the total cost is the same for either company?

Let x = length in feet. Set costs equal:

20x + 210 = 27.5x
210 = 7.5x
x = 210 / 7.5 = 28

So the fence must be 28 feet long.
