A long year-end status report for work is 130 pages long. You need to print 17 copies for a meeting next week. How much is the paper going to cost for those reports? Paper is sold in reams (500 pages) for $3.44 each

The first thing you should do in this case is to know how much paper you need to print for the 17 copies.
 We have then:
 (17) * (130) = 2210
 Then, you must calculate the number of reams you need:
 n = (2210) / (500) = 4.42
 You need 4 full reams and 42% of a fifth ream. So, the cost will be
 C = (4.42) * (3.44) = 15.2048 $
 The unit cost of each paper is:
 Cu = (15.2048) / (2210) = 0.00688 $
 answer
 the paper is going to cost 0.00688 $ for those reports
