590000+40000(6500000*1-3/4%)
\(590000+40000\times(6500000\times1-\frac{3}{4} \%)\)
= \(590000+40000\times(6500000-48750)\)
= \(590000+40000\times6451250\)
= \(590000+258050000000\)

The track team has 60 members.after the track meet 9 members rode home with the their parents instead of riding the team bus.what percent of the team rode home with their parents?create a model to prove your answer.
\(\frac{x}{9\ members}=\frac{100^{\ O}/ \ o }{60\ members} \ \ \ \ [ \times 9\ members\)
\(x=\frac{100^{\ o}/ \ o \ \times \ 9\ members}{60\ members}\)
x = 15%
