PLEASE HELP. I'M CONFUSED :'(
What are you confused on?
I typed out the function but is it correct and how do I graph it using a graphing device?
Unless you have a calculator that can graph two variables, you will simply solve for each variable independently and graph, so for instance, g=90-3c would be the graph for your goats per cow graph.
So my combination function is correct?
Yes, it certainly looks correct to me, but then again you stated as much when you asked about the plotting. :D
