A landscape architect plans to enclose a 1500 square foot rectangular region in a botanical garden. She will use shrubs costing $25 per foot along three sides and fencing costing $10 per foot along the north side.
If x is the length of fencing used, write a formula for the total cost in terms of x only.
(b) Find the length of fence that will minimize the total cost.
x =
Minimizing total cost?
