The number of jelly beans that Julie had in the end is repeated. Make the number of jelly beans that Julie had in the end the same. LCM of 1 and 4 is 4.
Number of jelly beans that Julie had more than Linda
= 32 u - 2 u
= 30 u
30 u = 210
1 u = 210 ÷ 30 = 7
Number of jelly beans that Linda had at first
= 2 u
= 2 x 7
= 14
Answer(s): 14
