20100 =
15 Emily spent: Emily's total = 1 : 5
Amount that Joelle spent
= 3 x 1 u
= 3 u
Amount that the three girls spent
= 1 u + 3 u + 212
= 4 u + 212
Amount that the three girls spent
= 1598 - 794
= $804
4 u + 212 = 804
4 u = 804 - 212
4 u = 592
1 u = 592 ÷ 4 = 148
Amount that Natalie and Joelle had in the end
= 794 - 4 u
= 794 - 4 x 148
= 794 - 592
= $202
Answer(s): $202
