Before starting, the answer to the 2nd problem is NOT y=3.9x+20 or y=4.1x-300. Those are the solutions to the first part of the question. The second part is asking for the TOTAL cost when you have "x" amount of feet, not just the cost of digging ONE foot. I posted earlier and received the above answers. The question I would like help with is at http://faculty.prairiestate.edu/skifowit/htdocs/projects/a07.htm Please help, I've been trying for so long. I do not need the graphs. I can do that once I have the equation.
