Answer:

The answer is "=24x+ \frac{28800}{x}+20"

Step-by-step explanation:

The perimeter of the fence =2x+y

cost of fence=12(2x+y)

cost of corner ports= 4 \times 5=20

cost of pen= 24x+12y+80.............(1)

area of pen=2400

xy=2400\\\\y=\frac{2400}{x}

cost c(x)=24x+ \frac{12 \times 2400}{x}+20

             =24x+ \frac{28800}{x}+20
