Question

Ella needed to get her computer fixed. She took it to the repair store. The technician at the store worked on the computer for 3 hours and charged her $61 for parts. The total was $226. Write and solve an equation which can be used to determine x, the cost of the labor per hour

Answer 1

Answer - equation is $226= 3x + $61
Answer to cost per hour is $55
Step by step
We know the total spent is $226
We know the labor hours is 3
We know the parts cost (y intercept) is $61
We need to find x the cost per hour
$226=3x +$61
Subtract $61 from both sides to isolate x
$165 = 3x
Now divide both sides by 3 to solve for x
$55 = x
You can check your work by substituting $55 for x in your equation
$226 = (3)(55) + $61
$226 = $165 + $61
$226 = $226
