Question

Caroline needed to get her computer fixed. She took it to the repair store. The technician at the store worked on the computer for 2. 75 hours and charged her $114 for parts. The total was $320. 25. Write and solve an equation which can be used to determine xx, the cost of the labor per hour. ​

Answer 1

Answer:

$75 an hour - (320.25 - 114) / 2.75

Step-by-step explanation:

First, we have to deduct the amount for parts ($114) from the total ($320.25). Once we find the diffrence (206.25), we can divide it by the amount of hours it took (2.75). This leaves us with the answer, $75 an hour.
