Answer:
Almost 5 reams of paper will be needed.
Step-by-step explanation:
Number of reams = 7
Each reams have pages = 500
Total pages he has = 7* 500 = 3500
Number of reports = 16
Pages each report has = 355
Total pages to be printed = 16* 355 = 5,680
Pages to be purchased = 5,680 - 3500
Pages to be purchased = 2,180
For calculating number of reams to be purchased, divide the number of pages with 500 as follows
Number of reams needed = 2,180/500
Number of reams needed = 4.36
As 4 reams will not be enough so he has to buy 5 reams i order to have required printing.
I hope it will help You!
