The formulas

\(\begin{aligned}M\amp =0.4x+3.1 \amp \qquad\amp \amp W\amp =0.36x+4.8\end{aligned}\)

describe the numbers (of thousands) of men and women enrolled in math courses at PCC \(x\) years after 2005. Give a simplified formula for the total number \(T\) of thousands of students at PCC taking math classes \(x\) years after 2005. Be sure to give the entire formula, starting with T=.
