Someone please help! Thanks!

Hannah's House of Music wants to purchase Transposelt, a system that transposes any song in its database and prints sheet music in the requested key. This system allows singers to obtain sheet music in keys that are suitable to their vocal range. The software for the system costs $10,300; a new computer and a laser printer costing 3,510 will be needed to run the system. Hannah estimates that the system will generate additional annual sales revenue of $23,800 and that annual cash expenditures will be $18,270. Hannah uses straight-line depreciation. The software, computer, and printer will have a useful life of five years. The system will have no salvage value at the end of its five-year useful life.
