40% =
40100 =
25 Eva spent: Eva's total = 2 : 5
Amount that Pamela spent
= 3 x 2 u
= 6 u
Amount that the three girls spent
= 2 u + 6 u + 294
= 8 u + 294
Amount that the three girls spent
= 2450 - 756
= $1694
8 u + 294 = 1694
8 u = 1694 - 294
8 u = 1400
1 u = 1400 ÷ 8 = 175
Amount that Roshel and Pamela had in the end
= 756 - 3 u
= 756 - 3 x 175
= 756 - 525
= $231
Answer(s): $231
