# How do you evaluate the function g(t) = 4/5t, when t=50?

Aug 7, 2015

$g \left(50\right) = 40$

#### Explanation:

To evaluate the function when $t = 50$, all you have to do is calculate the value of $g \left(t\right)$ when the variable $t$ is equal to $50$.

Your function can have different values depending on what value of $t$ is being used.

In your case, $g \left(50\right)$ will be

$g \left(50\right) = \frac{4}{5} \cdot 50$

You can simplify this to write

$g \left(50\right) = \frac{4}{\cancel{5}} \cdot {\cancel{50}}^{\textcolor{b l u e}{10}} = 4 \cdot 10 = \textcolor{g r e e n}{40}$
