3.If the software is to be replaced after one year, is it better to buy or make this software? 4.How much would they save by following your suggestion?

Based on the above case,please graph make and buy Total Cost (TC) at Q zero, Q equalization and Q 2,500 days using the provided graph. Make sure you clearly and accurately label the requested points on your graph(assume an average of 30 days per month, Q is in days and TC is CAD).
