Sarah D is going to produce a new CD. She has a pool of musicians that need to be organized to perform at the recording studio session. They all can play any of the instruments that she needs but due to various skill sets, they take different times to master the music on the different instruments. The times are listed in the table below.

a. There is only one practice/recording chamber and it can only house one musician at a time. Union rules limit each performer to one instrument per job. Since studio and rehearsal time cost money, Sarah D wants you to find the minimum time to record the parts.

b. Provide the solver sheets

c. If Foxy Fran is sick, how does Sarah D's recording assignment change? What instrument gets omitted from the CD?

d. Provide the solver sheets
