At a university, a student club wants to send out an individualized invitation letter to 1000 faculty for an upcoming donor event. Each letter requires the following steps, in order:

1. Write a personal message to the faculty member on the inside of a card (10 minutes). 2. Hand draw a scene with the club logo on the cover of the card with colored pencils. (15 minutes)

3. Cut out and form a special envelope for the card out of a sheet of premium paper. (3 minutes) 4. Seal the card in the envelope with glue, look up and write the address of the faculty member, and put a stamp on the card. (2 minutes)

(a) If the club utilized the principle of pipelining and had four workstations, one for each step above, and one person to work at each workstation, how many minutes would it take to complete the 1000 invitations? How does this compare to one person completing the entire task? Show your work.
