Refer to Problem 5.25 and answer the following questions.
(a) Plot the future worth for each project as a function of the interest rate (0% to 50%).
(b) Compute the project balance of each project at i = 12%.
(c) Compare the terminal project balances calculated in (b) with the results obtained in Problem 5.25(a). Without using the interest factor tables, compute the future worth on the basis of the project balance concept.
