The number of lollipops that Tiffany had in the end is repeated. Make the number of lollipops that Tiffany had in the end the same. LCM of 1 and 3 is 3.
Number of lollipops that Wendy had less than Tiffany
= 12 u - 5 u
= 7 u
7 u = 70
1 u = 70 ÷ 7 = 10
Number of lollipops that Tiffany had at first
= 12 u
= 12 x 10
= 120
Answer(s): 120
