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