The firm forecasts that it could sell a maximum of 4,000 A-100's this week and a maximum of 1,000 B-200's. Profits for the A-100 are $2.50 each, and profits for the B-200 are $3.00 each. For the production combination of 1,400 A-100's and 900 B-200's which resource does not have "slack"?
A. circuit boards (only)
B. assembly time (only)
C. both circuit boards and assembly time
