Using the answer from Problem 12-9, set up the equation to compute the after-tax rate of return for each scenario:

(a) A $5000 corporate bond costs $4600, paying $500 interest at the end of each year for the next 5 years. At the end of 5 years you get $5000.

(b) A federal-income-tax-free (on interest only) municipal bond costing $3000, paying $250 at the end of each year for 5 years, and $2500 at the end of the 5 years. State and local income taxes must be paid.

(c) A tax-deferred savings plan in which you invest $4000 for 5 years. The plan earns 8% annual interest and you get back your $4000 plus interest at the end of 5 years. Contributed by D. P. Loucks,Cornell University Corporate Taxes
