Financial management 15th edition, problem 16-18 (part e) the sensitivity analysis. This is where I am needing help.

e. If its customers began to pay late, this would slow down collections and thus increase the required loan amount. Also, if sales dropped off, this would have an effect on the required loan. Do a sensitivity analysis that shows the effects of these two factors on the max loan requirement. Assume the purchases of labor and raw material also vary by the sales adjustment factor.
