Question

If a plumber earns 22 dollars per job. Then he goes to 3 jobs but in addition he gets paid 38 dollars an hour. If with those 3 jobs he earned more than 350 dollars. Do you know how many hours the plumber worked?

Explain in full justification

Answer 1

No.

Explanation:

The problem only tells you that he earned more than 350 dollars. So it could be much, much higher, or it not be. If it told us a precise amount of money, we would be able to find out how many hours he worked.
