40100 =
25 Pamela spent: Pamela's total = 2 : 5
Amount that Jane spent
= 4 x 2 u
= 8 u
Amount that the three girls spent
= 2 u + 8 u + 232
= 10 u + 232
Amount that the three girls spent
= 1635 - 603
= $1032
10 u + 232 = 1032
10 u = 1032 - 232
10 u = 800
1 u = 800 ÷ 10 = 80
Amount that Mary and Jane had in the end
= 603 - 3 u
= 603 - 3 x 80
= 603 - 240
= $363
Answer(s): $363
