How many bouquets are there? ** There are 3 bouquets.
What is the total number of carnations? ** The total is the average times the number of bouquets, or 12*3=<<12*3=36>>36.
How many carnations are accounted for? ** There are 9+14=<<9+14=23>>23 accounted for.
How many carnations were in the third bouquet? ** The third included 36-23=<<36-23=13>>13 carnations.
