Adamson Corporation is considering four average-risk projects with the following costs and rates of return:

Project	Cost		Expected Rate of Return

2	3,000		15.00
3	5,000		13.75
4	2,000		12.50

The company estimates that it can issue debt at a rate of r_d = 9%, and its tax rate is 25%. It can issue preferred stock that pays a constant dividend of $4.00 per year at $54.00 per share. Also, its common stock currently sells for $38.00 per share; the next expected dividend, D₁, is $4.75; and the dividend is expected to grow at a constant rate of 4% per year. The target capital structure consists of 75% common stock, 15% debt, and 10% preferred stock.
