At her school’s spring carnival, Leslie is in charge of the balloon-launcher contest. In this contest, each team builds a catapult to launch water balloons at a target. Leslie gives a bucket of 12 water balloons to each team in the contest. In all, she gives out a total of 48 water balloons. Which equation can model this situation for n, the number of teams in the contest? a 48 = 12 + n b 48 = 12n c 48 = 12 - n d 48 = 12/n
