20100 =
15 Hazel spent: Hazel's total = 1 : 5
Amount that Tammy spent
= 3 x 1 u
= 3 u
Amount that the three girls spent
= 1 u + 3 u + 169
= 4 u + 169
Amount that the three girls spent
= 943 - 542
= $401
4 u + 169 = 401
4 u = 401 - 169
4 u = 232
1 u = 232 ÷ 4 = 58
Amount that Lucy and Tammy had in the end
= 542 - 4 u
= 542 - 4 x 58
= 542 - 232
= $310
Answer(s): $310
