40% =
40100 =
25 Penelope spent: Penelope's total = 2 : 5
Amount that Xandra spent
= 3 x 2 u
= 6 u
Amount that the three girls spent
= 2 u + 6 u + 101
= 8 u + 101
Amount that the three girls spent
= 2238 - 753
= $1485
8 u + 101 = 1485
8 u = 1485 - 101
8 u = 1384
1 u = 1384 ÷ 8 = 173
Amount that Dana and Xandra had in the end
= 753 - 3 u
= 753 - 3 x 173
= 753 - 519
= $234
Answer(s): $234
