The contractor's construction expenses and owner's payments for a construction project are expressed in then-current inflated dollars in the table below. The monthly interest rate required by the bank is 1.5 percent regardless of inflation. Suppose that the work is stopped for two months at the end of month 5 due to a labor strike while the monthly inflation rate is 0.5 percent. Under the terms of the contract between the owner and the contractor, suppose that the owner's payments will be delayed but not adjusted for inflation. Find the cumulative net cash flow with interest due to overdrafting for the following conditions: (a) if there were no labor strike and (b) when there is a strike for two months at the end of month 5
