The amount that Raeann has remains unchanged at first and in the end. Make the amount that Raeann has the same. LCM of 1 and 4 is 4.
Amount that Nicole spent
= 12 u - 1 u
= 11 u
11 u = 220
1 u = 220 ÷ 11 = 20
Amount that Raeann brought along less than Nicole
= 12 u - 4 u
= 8 u
= 8 x 20
= $160
Answer(s): $160
