Years later and the printer ink business is still booming, but you begin to get greedy. You decide that you will sell the ink in proprietary cartridges that become obsolete after a specific amount of time, after which they stop working. You need to purchase a maintenance contract for the manufacturing equipment needed to build these cartridges. No maintenance will be needed until year 5. At the end of year 5, the contract will cost $11, 300 per year, increasing by $400 each year, with the contract ending after year 10. a) Draw an accurate cash flow diagram for this scenario, as well as scenarios for (b) and (c). (b) Instead of waiting, you decide to fund the contract with a lump sum payment in Year 0. What initial payment would be required? (c) After considering the lump sum payment, you decide instead to fund the cost of the contract (for years 5 through 10) by making equal annual instalments in years one through five, Assume a rate of return equal to 13% per year
