40100 =
25 Gillian spent: Gillian's total = 2 : 5
Amount that Lynn spent
= 4 x 2 u
= 8 u
Amount that the three girls spent
= 2 u + 8 u + 185
= 10 u + 185
Amount that the three girls spent
= 1848 - 513
= $1335
10 u + 185 = 1335
10 u = 1335 - 185
10 u = 1150
1 u = 1150 ÷ 10 = 115
Amount that Gwen and Lynn had in the end
= 513 - 3 u
= 513 - 3 x 115
= 513 - 345
= $168
Answer(s): $168
