Okay, well there seems to be a problem with how you've interpreted the 3000 square feet. Remember that 3000 is an area, not a perimeter. So, in essence, your cost equation is actually alright, but what you're replacing y with is the problem. Hope this helps and next time please do identify yourself.
Students should feel free to use this blog as a vehicle for exchange of ideas and concepts. If some topics in Calculus are particularly challenging then try browsing some of the "Reference Websites" included in this blog. There you will find some neat tutorials for concepts we have covered in class and some great visualization tools as well. Ofcourse, Calculus is not without its history and so there are many links dedicated to the history of calculus and the history of math in general.

aight so i need some help on #19,
I set it up so that two paralell sides are called x and the others called y.
Cost=10x+50y+25x or C=35x+50y
i also know that my perimeter equation is
P=x+x+y+y or P=2x+2y and you know
3000=2x+2y
so then i solved for y so that its y=1500-x
however when i plugged in y into my cost equation i got C=35x+50(1500-x)
I think my cost equation is messed up
