She wants the entire enclosed area to be 2400 square feet. Lastly,she needs four corner that costs $5 each ? Let x represent the length of each side of the pen perpendicular to the house and let y represent the length of the side of the pen parallel to the

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) $=24x+ \frac{12 \times 2400}{x}+20$

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