The number of jelly beans that Eva had in the end is repeated. Make the number of jelly beans that Eva had in the end the same. LCM of 1 and 2 is 2.
Number of jelly beans that Eva had more than Julie
= 8 u - 3 u
= 5 u
5 u = 55
1 u = 55 ÷ 5 = 11
Number of jelly beans that Julie had at first
= 3 u
= 3 x 11
= 33
Answer(s): 33
