Joe's commercial laundry has contracts to wash bed sheets for hotels. Joe can receive one batch of sheets every minute. Then the sheets are washed which takes $20$ minutes and then dried which takes another $30$ minutes. Joe has five wash machines and seven dryers that can each process one batch of sheets. The batch of sheets is ironed which takes another $10$ minutes and there are two employees ironing sheets. Finally, Joe packages the sheets and bills the customer, which takes $2$ minutes.

a$.$ What is the capacity of the laundry system and what is the bottleneck?

b$.$ What is the average throughput time of a batch of sheets?
