A local arcade charges $15.00 for unlimited play time for the first hour, then $5.00 per additional hour. On a piece of paper, write an equation that represents the cost to play, C
, based on the number of hours played, h. Then use the equation to calculate how much it would cost to play for three hours. Enter your answer for C
, including cents.(1 point)

To represent the cost to play at the arcade based on the number of hours played, we can create a piecewise equation. The cost \( C \) can be expressed as follows:

\[
C =
\begin{cases}
15 & \text{if } h \leq 1 \\
15 + 5(h - 1) & \text{if } h > 1
\end{cases}
\]

This equation shows that:
- For up to 1 hour of play, the cost is $15.00.
- For every additional hour played beyond the first hour, it costs $5.00.

Now, let's calculate the cost for 3 hours of play.

Since 3 hours is greater than 1, we will use the second part of our piecewise function:

\[
C = 15 + 5(3 - 1)
\]
\[
C = 15 + 5(2)
\]
\[
C = 15 + 10
\]
\[
C = 25
\]

So, the cost to play for three hours is \( C = 25.00 \).

The final answer is:
\[
\text{Cost } C = \$25.00
\]
