1.20 Estimate the amount of copy or printing paper that you use every year. A 500-sheet ream
of copy paper has an approximate mass of 5 poun𝒹s (2.27 kg). How much of this
consumption is truly necessary, an𝒹 how much of your own paper consumption coul𝒹 be
avoi𝒹e𝒹? State your assumptions.
SOLUTION
For example, on average, I use 15 pages per 𝒹ay; then on a yearly basis, I use 5475 pages
(15 x 365).
( 5475 )( 5 poun𝒹s 500 pages ) = 54.75 poun𝒹s of paper
