The printer in Nate and Beth's office was out of paper. So, they put a ream of paper in the printer, 500 sheets. Nate then printed 72 sheets. Beth then added 30 sheets of paper to the printer.
What was the net change in the number of pieces of paper in the printer from after they added the ream of paper until after Beth added more paper?
