40100 =
25 Jean spent: Jean's total = 2 : 5
Amount that Tammy spent
= 2 x 2 u
= 4 u
Amount that the three girls spent
= 2 u + 4 u + 123
= 6 u + 123
Amount that the three girls spent
= 1103 - 536
= $567
6 u + 123 = 567
6 u = 567 - 123
6 u = 444
1 u = 444 ÷ 6 = 74
Amount that Lynn and Tammy had in the end
= 536 - 3 u
= 536 - 3 x 74
= 536 - 222
= $314
Answer(s): $314
