The number of candy canes that Erika had in the end is repeated. Make the number of candy canes that Erika had in the end the same. LCM of 1 and 2 is 2.
Number of candy canes that Erika had more than Abi
= 8 u - 5 u
= 3 u
3 u = 30
1 u = 30 ÷ 3 = 10
Number of candy canes that Abi had at first
= 5 u
= 5 x 10
= 50
Answer(s): 50
