16. AFX Industries purchased some agricultural land at the edge of a large metropolitan area for $400,000 five years ago. In order to have the land classified as agricultural for property tax purposes, the company has been leasing the property to neighboring farmers. The before-tax return from leasing the property is $12,000 per year. This company's corporate tax rate is 46 percent. If the company sells the land for $500,000 today, what is the internal rate of return on this investment?
