14 Natalie and Rachel had the same amount of money in the end. Make the amount that each had in the end the same. LCM of 1 and 3 is 3.
Amount that Natalie had more than Rachel at first
= 15 u - 4 u
= 11 u
11 u = 220
1 u = 220 ÷ 11 = 20
Amount that Natalie had in the end
= 3 u
= 3 x 20
= $60
Answer(s): $60
