The maximum number of hours the repairman estimated for the job is 5.
Step-by-step explanation:
It's simple. First, all you have to do is start with the budget he gave you and subtract the fixed price.
225 - 35 - 40 = 150
Then, use the money you have left over (150) and divide by how much he pays per hour which equals 5.
150/30 = 5
