Jelly Candies

Abelia, Baird, Cala, Dallas, and Edina were trying to guess how many jelly candies are there in a box. Abelia assumed that there were 30, Baird said 28, Cala supposed there were 29, Dallas assumed that 25, and Edina said 26. Two were off the mark by 1, one was wrong by 4, and one by 3. But one was still correct.
