40100 =
25 Lynn spent: Lynn's total = 2 : 5
Amount that Olivia spent
= 3 x 2 u
= 6 u
Amount that the three girls spent
= 2 u + 6 u + 201
= 8 u + 201
Amount that the three girls spent
= 1718 - 701
= $1017
8 u + 201 = 1017
8 u = 1017 - 201
8 u = 816
1 u = 816 ÷ 8 = 102
Amount that Betty and Olivia had in the end
= 701 - 3 u
= 701 - 3 x 102
= 701 - 306
= $395
Answer(s): $395
