A photocopy machine is initially loaded with 5,000 sheets of paper. The machine starts a large job
and copies at a constant rate. After 20 minutes, it has
used 30% of the paper. Which of the following
equations models the number of sheets of paper, P,
remaining in the machine m minutes after the
machine started printing?
A p = 5,000 - 20m
B) p = 5,000 - 75m
m
c) p = 5,000(0.3) 20
m
D) p = 5,000(0.7) 20
