12 Emma spent: Emma's total = 1 : 2
Amount that Tammy spent
= 4 x 1 u
= 4 u
Amount that the three girls spent
= 1 u + 4 u + 195
= 5 u + 195
Amount that the three girls spent
= 1846 - 656
= $1190
5 u + 195 = 1190
5 u = 1190 - 195
5 u = 995
1 u = 995 ÷ 5 = 199
Amount that Mary and Tammy had in the end
= 656 - 1 u
= 656 - 1 x 199
= 656 - 199
= $457
Answer(s): $457
