The CFO of The Fun Factory is investigating the possibility of investing in a three dimensional printer that would cost $20,000. The printer would eliminate the need to have prototypes of new toys be produced by a third party. The cost of having the prototypes manufactured by the third party is about $8,000  per year. The printer would have a useful life of five years with no salvage value with expected annual operating costs of $3,000 per year.

Required:
Compute the simple rate of return on the printer.
