Answer:
3 hours was spent on labor
Step-by-step explanation:
<u>Key skills needed: Creating an equation, Solving an equation</u>
1) The total cost is 329.00 (or 329). The parts are 125.00 (or 125), and the labor is 68 per hour.
2) If we say h is the number of hours of labor, then we can create this equation --> (or 68 multiplied by "h") 68h would be the cost of labor, and we need to find the number of hours (h) as a number.
3) We can create this equation -->
--> This equation can be made as the total cost (329) is equal to the parts (125) and the labor (68h)
4) Subtract 125 from both sides to get 68h by itself
--> 329 - 125 = 204 so 204 = 68h
--> Divide by 68 on both sides (204 divided by 68 is 3)
--> This means that h is 3.
Therefore, the number of hours spent on labor is 3.
