30% =
30100 =
310 Joelle spent: Joelle's total = 3 : 10
Amount that Ivory spent
= 4 x 3 u
= 12 u
Amount that the three girls spent
= 3 u + 12 u + 217
= 15 u + 217
Amount that the three girls spent
= 2281 - 759
= $1522
15 u + 217 = 1522
15 u = 1522 - 217
15 u = 1305
1 u = 1305 ÷ 15 = 87
Amount that Lynn and Ivory had in the end
= 759 - 7 u
= 759 - 7 x 87
= 759 - 609
= $150
Answer(s): $150
