A landscape architect plans to enclose a 1300 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.



(a) If x is the length of fencing used, write a formula for the total cost in terms of x only.

C(x) =



(b) Find the length of fence that will minimize the total cost.

x = feet



(c) Find the minimum total cost. Give your answer to the nearest penny

a) C(x)= 3*25*x+ 1*10*x

= 75x+10x



C(x)=75x+10x



b) Length is 1300 ft. There is four sides which equalls 4x.



4x=1300ft

x=1300ft/4

x=325 ft



c) C(x)= 75(325)+10(325)

= 10590125

cost is $10,590,125.00
