Please help with solution or explanation for the following problem:
Problem: Acme Manufacturing is a decentralized corporation. Divisions are treated as investment centers. In recent years, Acme has been running about 11% ROA for the corporation as a whole, and has a cost of capital of 9%. One of their most profitable divisions is Turner Products, which last year had ROA of 17% ($1,700,000 operating income on assets of $10,000,000). Turner has an opportunity to expand one of its plants to produce a promising new product. The expansion will cost two million dollars, and is expected to increase operating earnings to $2,100,000. What factors should Turner's manager and her supervisor, the VP of operations, consider in deciding whether to go forward with the expansion? Show any necessary calculations.
