Adelaide bought twice the number of ducks that Ephraim bought, while Ephraim bought 45 fewer ducks than Kolton. If Adelaide bought 30 ducks, what's the average number of ducks the three bought?
Step-by-step reasoning process: If Adelaide bought 30 ducks, Ephraim bought 30 ducks / 2 = 15 ducks. Since Ephraim bought 45 fewer ducks than Kolton, Kolton bought 45 ducks + 15 ducks = 60 ducks. The total number of ducks the three bought is 60 ducks + 15 ducks + 30 ducks = 105 ducks. The average number of ducks each bought is 105 ducks / 3 people = 35 ducks / person.
