Lucas went to the store with $20 and needed to buy 3 avocados that cost $2 each. How much change does he bring home?
assistant
How much do the avocados cost? ** The avocados cost 6 because 3 x 2 = <<3*2=6>>6
How much change does he bring home? ** He brings home $4 in change because 20 - 6 =<<20-6=14>>14
