Sarah needed to get her computer fixed. She took it to the repair store. The technician at the store worked on the computer for 5.25 hours and charged her $133 for parts. The total was $579.25. Which equation could be used to determine cc, the cost of labor per hour?

To find the cost of labor per hour (denoted as $ c $), we can set up an equation based on the information provided:

- The technician worked for 5.25 hours.
- The cost for parts was $133.
- The total amount Sarah was charged was $579.25.

The equation will include the cost of labor for the hours worked plus the cost of parts, which equals the total amount charged. Therefore, the equation is:

\[
5.25c + 133 = 579.25
\]

Here, $ c $ represents the cost of labor per hour.

Would you like to solve for $ c $ or have more details on how to solve the equation?

Here are 5 related questions:
1. How would you solve the equation to find the value of $ c $?
2. If the technician had worked for 6 hours instead, what would the total cost be?
3. What is the total cost of labor if the hourly rate is $85?
4. How much would Sarah have been charged if the parts cost $150 instead of $133?
5. What percentage of the total bill is the cost of labor?

**Tip:** When solving linear equations, always isolate the variable on one side of the equation to find its value.
