Hello all, I have theses three questions that I need assistance on. Whom ever is able to help, I would like to request it in Excel or detailed steps with dumbed down terminology. I am new to this and while I do need the answer, I am equally interested in the steps. THANK YOU!!

1- Calculating Project NPV Raphael Restaurant is considering the purchase of a $9,000 egg maker. The egg maker has an economic life of five years and will be fully depreciated by the straight-line method. The machine will produce 1,500 eggs per year, with each costing $2.30 to make and priced at $4.75. Assume that the discount rate is 14 percent and the tax rate is 34 percent. Should Raphael make the purchase?

2- Calculating Project NPV   Down Under Boomerang, Inc., is considering a new three-year expansion project that requires an initial fixed asset investment of $1.4 million. The fixed asset will be depreciated straight-line to zero over its three-year tax life, after which it will be worthless. The project is estimated to generate $1,120,000 in annual sales, with costs of $480,000. The tax rate is 35 percent and the required return is 12 percent. What is the project’s NPV?

3-Financial Break-even   L.J.’s Toys Inc. just purchased a $390,000 machine to produce toy cars. The machine will be fully depreciated by the straight-line method over its five-year economic life. Each toy sells for $25. The variable cost per toy is $11, and the firm incurs fixed costs of $280,000 each year. The corporate tax rate for the company is 34 percent. The appropriate discount rate is 12 percent. What is the financial break-even point for the project?
