Question 496146: A wall is to be constructed around 3 sides of a rectangle of area 480 square yards, with a fence running the length of one side. The construction cost for the wall is $19 per linear yard, while the fence will cost $7 per linear yard. Determine a model for the total cost, C, of the project as a function of the length of the fence, x. Answer by cleomenius(959) (Show Source):
You can put this solution on YOUR website! We are going to need to assign a variable d for the difference between the length and the width.
f(x) = (x)19 + (x)7 + 2(x + d)(7) .
This model is assuming we have already determined values for x and d.
