The number of chocolate bars that Ivory had in the end is repeated. Make the number of chocolate bars that Ivory had in the end the same. LCM of 1 and 2 is 2.
Number of chocolate bars that Ivory had more than Jane
= 10 u - 2 u
= 8 u
8 u = 88
1 u = 88 ÷ 8 = 11
Number of chocolate bars that Jane had at first
= 2 u
= 2 x 11
= 22
Answer(s): 22
