The number of candy canes that Min had in the end is repeated. Make the number of candy canes that Min had in the end the same. LCM of 1 and 2 is 2.
Number of candy canes that Olivia had less than Min
= 10 u - 3 u
= 7 u
7 u = 84
1 u = 84 ÷ 7 = 12
Number of candy canes that Min had at first
= 10 u
= 10 x 12
= 120
Answer(s): 120
