Solve the capital budgeting problem in Problem 12.21(a) using the linear programming model and a spreadsheet.

Problem 12.21

A capital-budgeting problem is defined as follows: three projects are to be evaluated at a MARR of 12.5% per year. No more than $3.0 million can be invested.

(a) Use a spreadsheet to select from the indepen­dent projects.

(b) After some study, it was determined that the life of project 3 can be increased from 5 to 8 years for the same $1 million investment; however, the estimated annual NCF would remain steady from year 5 on. Use Goal Seek to determine the NCF in year 1 and be­yond for project 3 (as a bundle of one proj­ect) to have the same PW as the best bundle in part (a). All other estimates remain the same. With these new NCF and life esti­mates, what are the best projects for investment?


Enter the NCF values from Problem 12.21 into the capital budgeting template and a constraint of b = $3,000,000 into Solver. Select projects 1 and 2 for Z = $199,496 with all $3 million invested.
