Your primary job during this time is to provide the necessary forms each day: Day 1 2 3 4 [ 5 6 7 8 9 10 Forms |50 60 80 70 50 |60 90 80 50 100 needed To meet these requirements you have three options: 1) you can purchase new forms for $200 each; 2) you can recondition used forms using a standard process that takes 4 days and costs $25 per form: or 3) you can recondition forms using a special "fast" process that takes 2 days and costs $75 each. Assume that the company supplying you with forms has sufficient inventory to supply all new forms if necessary. Also, you have no forms prior to the start of this operation. Formulate a linear program that will suggest a strategy for meeting the demand for forms at least total cost
