Question 112615: I am having a hard time writing the formula needed in order to solve this equation; A farmer wishes to fence in a pasture along a straight highway. The pasture is to contain 500 sq ft of land and be rectangular. If the fencing along the highway is heavy duty and costs $3 per foot, while the material for the remaining three sides costs $2 per foot, find the dimensions of the pasture with the minimum fencing cost.

let x="highway dimension", so 500/x="other dimension"

c=3x+2x+2(2(500/x)) ___ c=5x+2000/x
