A large grocery corporation has developed the following schedule for converting frozen food display cases to use CFC-free refrigerant:

Week ....................................Units
1 .............................................20
2 ............................................65
3 ..........................................100
4 ..........................................140
5 ..........................................120

Historically, the learning rate has been 90 percent on such projects. The budget allows for a maximum of 40 direct labor employees per week and a total of 8,000 direct labor hours for the entire schedule. Assume 40 work hours per week. If the first unit took 30 hours to convert, is this schedule feasible? If not, how can it be altered? Are additional costs involved in altering it?
