Let's break down the problem step by step.

• The technician worked on Rashon's computer for 4.25 hours.
• The technician charged him $141 for parts.
• The total amount Rashon paid was $332.25.
• The variable $x$ represents the cost of labor per hour.

The equation will consist of two components: the labor cost and the parts cost.

1. The labor cost is $4.25x$, where $x$ is the labor cost per hour and 4.25 is the number of hours.
2. The parts cost is $141.

The total cost is the sum of these two components:

$4.25x + 141 = 332.25$

Solving the equation:

$4.25x + 141 = 332.25$

Subtract 141 from both sides to isolate the term with $x$:

$4.25x = 332.25 - 141$

$4.25x = 191.25$

Now, divide both sides by 4.25 to find $x$:

$x = \frac{191.25}{4.25}$

$x = 45$

Conclusion:

The cost of labor per hour is $45.

2. How much would the parts need to cost to make the total $400?
3. If the technician worked 3 more hours, how much would Rashon pay in total?
4. How much would Rashon save if the labor cost was $40 per hour?
5. What would the total cost be if only the parts were $200 and no labor was required?
