can anyone help me with these problems i have left? thanks!

Sharkey's Fun Center contains a number of electronic games as well as a miniature golf course and various rides located outside the building. Paul Sharkey, the owner, would like to construct a water slide on one portion of his property. Mr. Sharkey has gathered the following information about the slide: a. Water slide equipment could be purchased and installed at a cost of $495, 030. According to the manufacturer, the slide would be usable for 12 years after which it would have no salvage value. b. Mr. Sharkey would use straight-line depreciation on the slide equipment. c. To make room for the water slice, several rides would be dismantled and sold. These rides are fully depreciated, but they could be sold for $122, 250 to an amusement park in a nearby city. d. Mr. Sharkey has concluded that about 50,000 more people would use toe water slide each year than have been using the rides The admission price would be $4.80 per person (the same price that the Fun Canter has been charging for the old rides). e. Based on experience at other water slides Mr. Sharkey estimates that annual incremental operating expenses for the slide would be: salaries, $93,000; insurance, $5, 600; utilities, $14, 400; and maintenance, $11, 200. Required: Prepare an income statement showing the expected net operating in core each year from the water slide. 2a. Compute toe simple rate of return expected from the water slide. 2b. Based on the above computation, would the water slide be constructed if Mr. Sharkey requires a simple rate of return of at least 16% on all investments? Yes No 3a. Compute the payback period for the water slide. (Round your answer to 2 decimal places.) 3b. If Mr. Sharkey accepts any project with a payback period of five years or less, would the water slide be constructed? Yes No
