Green Forever’s challenge (see Problem S5.12) is to determine which design alternative is the better environmental choice if it uses a different battery for the Premium Mate. The alternate battery revenue and costs are as follows:

a) What is the revenue retrieval for the GF Deluxe?

b) What is the revenue retrieval for the Premium Mate?
