Question

sophie needed to get her computer fixed. she took it to the repair store. the technician at the store worked on the computer for 4 hours and charged her $127 for parts. the total was $227. write and solve an equation which can be used to determine $x$, the cost of the labor per hour. answer attempt 1 out of 3 equation: answer: $x = $

Explanation:

Step1: Set up the equation

The cost of labor is the number of hours times the cost per - hour ($4x$), plus the cost of parts ($127$) equals the total cost ($227$). So the equation is $4x + 127=227$.

Step2: Isolate the term with $x$

Subtract 127 from both sides of the equation: $4x+127 - 127=227 - 127$, which simplifies to $4x = 100$.

Step3: Solve for $x$

Divide both sides of the equation by 4: $\frac{4x}{4}=\frac{100}{4}$, so $x = 25$.

Answer:

Equation: $4x + 127=227$
