Answer:

Equations 2 and 4?

Step-by-step explanation:

It sounds like there are two separate equations for this problem depending if the time spent on the job is more, or less than or equal to 3. If the job is more than 3 hours the equation would be number 2. If the job takes less or equal to three hours the equation would be 4. I hope this helps.
