50% =
50100 =
12 Mary spent: Mary's total = 1 : 2
Amount that Jaslyn spent
= 3 x 1 u
= 3 u
Amount that the three girls spent
= 1 u + 3 u + 200
= 4 u + 200
Amount that the three girls spent
= 1032 - 620
= $412
4 u + 200 = 412
4 u = 412 - 200
4 u = 212
1 u = 212 ÷ 4 = 53
Amount that Nicole and Jaslyn had in the end
= 620 - 1 u
= 620 - 1 x 53
= 620 - 53
= $567
Answer(s): $567
