Question

Hello All,
I am stuck on this question for homework, help appreciated ( I really only need the answer to number one)

A new high school opened seven years ago. The number of members, M, in the
high school marching band can be modeled by
where y is the number of years since the school opened:

M= (-1316y - 6387)/(3.89y - 100) , 0 ≤ y ≤ 7

The number of trumpet players, T, in the same marching band can be modeled
by

(-245y-550)/(1.79y-100) , 0 ≤ y ≤ 7

where y is the number of years since the school opened.
1. Write a model to find the percent of trumpet players, T, in the marching
band for each year.
