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?
500-72+30 = 458 sheets left
Net Change = 458-500 = -42 Sheets. = A
decrease of 42 sheets.
42

Thanks so much it really helped alot
To find the net change in the number of sheets of paper in the printer, we need to calculate the initial number of sheets and the final number of sheets.
Initially, they added a ream of paper which is 500 sheets, so the initial number of sheets is 500.
Nate then printed 72 sheets, which means we need to subtract that from the initial number of sheets:
500 - 72 = 428
Afterward, Beth added 30 sheets, so we need to add that to the current number of sheets:
428 + 30 = 458
Finally, we find the net change by subtracting the initial number of sheets from the final number of sheets:
458 - 500 = -42
Therefore, the net change in the number of sheets of paper in the printer is -42, indicating a decrease of 42 sheets.
