12 Joelle spent: Joelle's total = 1 : 2
Amount that Tammy spent
= 2 x 1 u
= 2 u
Amount that the three girls spent
= 1 u + 2 u + 202
= 3 u + 202
Amount that the three girls spent
= 1326 - 677
= $649
3 u + 202 = 649
3 u = 649 - 202
3 u = 447
1 u = 447 ÷ 3 = 149
Amount that Olivia and Tammy had in the end
= 677 - 1 u
= 677 - 1 x 149
= 677 - 149
= $528
Answer(s): $528
