Given: The technician worked for 3.5 hours and charged $197 for parts.
The total cost was $494.50.
x is the cost of the labor per hour.
To find: The value of x
Solution: According to the given information, we can frame an equation as given below.
3.5x + 197 = 494.50
⇒ 3.5x = 494.50 - 197
⇒ 3.5x = 297.5
⇒ x = 297.5/3.5
⇒ x = 85
Therefore, the cost of the labor per hour, that is, x is $85.
