Suppose you work for a small farm owner, and you are asked to calculate a rate of return for two projects to determine which project should be selected. Project A has a total life of $3$ years with a discount rate of $12\%$ and Project B has a similar total life with a discount rate of $15\%.$ The expected cash flows of the projects are given in the table below:

$\backslash$table$[[$Year$,$Project A$,$Project B$],[0,-1,000,-800],[1,500,300],[2,700,600],[3,1,000,800]]$

What investment technique would be appropriate and explain which project you would recommend to the owner?
