Barbie enjoys buying jewelry. One day, she bought 12 pairs of earrings, and gave half of them to Alissa, making Alissa's total number of collections to be triple the number of earrings she was given. How many earrings does Alissa have now?
If 1 pair of earrings equals 2 earrings, then Barbie bought 12*2=<<12*2=24>>24 earrings.
Half of 24 earrings is 24/2=<<24/2=12>>12 earrings
If receiving 12 earrings tripled Alissa's collection, then she now has 12*3=<<12*3=36>>36 earrings.
