Jenny Chu can comfortably produce 3 specialty industrial signs in one month. Assume a 20-day work month. If Jenny brings on an apprentice from the design department of the local engineering college, she can produce 4 signs in one month.

a) What are the design and effective capacities for Jenny Chu’s sign shop?

b) If Jenny begins to produce 3.25 signs per month without the additional help, compute the capacity utilization for both measures. What can you conclude?
