Aphotocopy 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 equals, 5,000 minus 20 m b. p equals, 5,000 minus 75 m c. p equals 5,000 times, 0.3, to the power of the fraction m over 20 d. p equals 5,000 times, 0.7, to the power of the fraction m over 20
