50100 =
12 Vanessa spent: Vanessa's total = 1 : 2
Amount that Joelle spent
= 3 x 1 u
= 3 u
Amount that the three girls spent
= 1 u + 3 u + 250
= 4 u + 250
Amount that the three girls spent
= 1402 - 672
= $730
4 u + 250 = 730
4 u = 730 - 250
4 u = 480
1 u = 480 ÷ 4 = 120
Amount that Shannon and Joelle had in the end
= 672 - 1 u
= 672 - 1 x 120
= 672 - 120
= $552
Answer(s): $552
