Question

rashon needed to get his computer fixed. he took it to the repair store. the technician at the store worked on the computer for 4.25 hours and charged him $141 for parts. the total was $332.25. write and solve an equation which can be used to determine $x$, the cost of the labor per hour.
answer attempt 1 out of 2
equation:
answer: $x = $

Explanation:

Step1: Set up the equation

The total cost is the sum of the cost of parts and the cost of labor. The cost of labor is the number of hours times the cost per - hour. So the equation is $4.25x + 141=332.25$.

Step2: Isolate the term with $x$

Subtract 141 from both sides of the equation:
$4.25x+141 - 141=332.25 - 141$
$4.25x = 191.25$

Step3: Solve for $x$

Divide both sides of the equation by 4.25:
$x=\frac{191.25}{4.25}$
$x = 45$

Answer:

Equation: $4.25x + 141 = 332.25$
