12-88.

Beethoven wrote nine symphonies and Mozart wrote 27 piano concertos. What situation could this function describe? Homework Help ✎

If the local radio station KALG wants to play two pieces, a Beethoven symphony and then a Mozart concerto, in how many ways can this be done?

The station manager has decided that on each successive night (seven days a week), a Beethoven symphony will be played, followed by a Mozart concerto, followed by a Schubert string quartet (there are 15 of those). How long could this policy continue before exactly the same program would have to be repeated?

9(27) = 243

Combine the ways of part (a) with the 15 Schubert string quartets.
