110 Min and Julie had the same amount of money in the end. Make the amount that each had in the end the same. LCM of 2 and 9 is 18.
Amount that Min had less than Julie at first
= 45 u - 20 u
= 25 u
25 u = 525
1 u = 525 ÷ 25 = 21
Amount that Julie had at first
= 45 u
= 45 x 21
= $945
Answer(s): $945
