The number of lollipops that Emily had in the end is repeated. Make the number of lollipops that Emily had in the end the same. LCM of 1 and 3 is 3.
Number of lollipops that Elyse had less than Emily
= 18 u - 2 u
= 16 u
16 u = 144
1 u = 144 ÷ 16 = 9
Number of lollipops that Emily had at first
= 18 u
= 18 x 9
= 162
Answer(s): 162
