50% =
50100 =
12 Min spent: Min's total = 1 : 2
Amount that Tammy spent
= 2 x 1 u
= 2 u
Amount that the three girls spent
= 1 u + 2 u + 275
= 3 u + 275
Amount that the three girls spent
= 1471 - 644
= $827
3 u + 275 = 827
3 u = 827 - 275
3 u = 552
1 u = 552 ÷ 3 = 184
Amount that Elyse and Tammy had in the end
= 644 - 1 u
= 644 - 1 x 184
= 644 - 184
= $460
Answer(s): $460
