Given the ratio:
[tex]\frac{3}{7}:1:\frac{2}{5}[/tex]Therefore we add the ratios:
[tex]\frac{3}{7}+1+\frac{2}{5}=\frac{64}{35}[/tex]So, the winning is given by:
Amina
[tex](\frac{3}{7}\div\frac{64}{35})\times10210=\frac{3\times35}{7\times64}\times10210=\frac{105}{448}\times10210=2392.97[/tex]Lloyd
[tex](1\div\frac{64}{35})\times10210=\frac{1\times35}{1\times64}\times10210=\frac{35}{64}\times10210=5583.59[/tex]Katlyn
[tex](\frac{2}{5}\div\frac{64}{35})\times10210=\frac{2\times35}{5\times64}\times10210=\frac{70}{320}\times10210=2233.44[/tex]Answer:
Amina - $2392.97
Lloyd - $5583.59
Katlyn - $2233.44
