Start by consider what the options are for the number of people turning up for the coach and minibus, such that the coach is not overbooked.

In this case:

In order for the coach not the be overbooked, we require.

(14 or less turn up for the minibus (i.e. no extras requiring the coach) and 48 or less turn up for the coach) or (15 turn up for the minibus (means 1 for the coach) and 47 or less turn up for the coach).
