An apprentice productively working a 40-hour week earns more wages and is worth considerably more to the local union and the ind
ustry than one who works only 30 hours per week. Consider two apprentices, A and B, working the same job at the same scale. Apprentice A works 40 hours and is paid $160.00 from which $4.80 is paid to the local union. Apprentice B only works 30 hours. How much will the local union receive in dues for the 30 hours work?
You can get this by determining that the rate of which they are paid is $4 an hour (divide the total by the amount of hours). Then you can find the rate of which they collect dues by dividing the amount they paid by their total (3%).
Using those numbers you can find the total amount the second person paid.
