Average national teachers salaries can be modeled using the equation y=9.25(1.06)^n , where y is the salary in thousands of dollars and n is the number of years since 1970

Agraph the function
Busing this model, what can a teacher expect to have as a salary in year 2020?

Please help !

Verified Answer :

\(y=9.25(1.06)^{n}\)
Plug in \(n\) to find \(y\).
\(n\) would be \(50\) because \(2020-1970=50\).

Use order of operations to solve.
\(y=9.25(1.06)^{50} \\ y=9.25(18.42) \\ y=170.39\)

Since \(y\) is the salary in thousands, multiply \(170.39\) by \(1000\).
\(170.39*1000=17039\)

A teacher can expect to have about $17,039 as a salary in the year 2020.
