#1: Mmmmm....donuts

A baker sells donuts for $0.99 each for less than 18 donuts. For 18 or more donuts, the baker charges $14.99 plus $0.79 for each additional donut.

Write the piecewise function (constraints) describing this situation.

Use the format \( f(x) = \{ \) first formula, when \( x \) (first inequality)
second formula, when \( x \) (second inequality) \( \} \).

For example: $0.99 each for less than a dozen (12) and $9.99 for a dozen plus $0.79 for each additional donut would look like this: \( f(x) = \left\{
\begin{array}{lr}
0.99x, & \text{when } x < 12 \\
9.99 + 0.79(x - 12), & \text{when } x \geq 12
\end{array}
\right. \)
