A pastry shop has fixed costs of $\$280$ per week and variable costs of $\$9$ per box of pastries. The shop’s costs per week in terms of $x$, the number of boxes made, is $280+9x$. We can divide the costs per week by the number of boxes made to determine the cost per box of pastries.

$\frac{280+9x}{x}$

Notice that the result is a polynomial expression divided by a second polynomial expression. In this section, we will explore quotients of polynomial expressions.
