You didn't put any numbers or variables in your problem so I'm just going to guess what you meant:
Tony made zlotys (he's working in Poland) for hours of work. At the same rate, how much would he make for hours of work?
If he made monetary units for time units of work, then he makes monetary units per time unit. Hence he would make a total of monetary units if he worked time units.
