Question

kevin uses his college photocopier machine to photocopy at the rate of $0.08 per page. he decides to rent a photocopier machine for $90 a year. The cost of photocopying using the rented machine is $0.03 per page.Part A: Write an inequality that can be used to calculate the number of pages that kevin should photocopy in a year so that the amount he pays for the rented machine is less than the college machine. Define the variable used. Part B: How many pages should kevin print in a year to justify renting the photocopier? Show your work.

Answer 1

.08p > 90 + .03p (p = number of pages)

.08p > 90 + .03p (subtract .03p from both sides)
.08p - .03p > 90
.05p > 90 (divide both sides by .05)
p > 90/.05
p > 1800

check..
.08(1801) > 90 + .03(1801)
144.08 > 90 + 54.03
144.08 > 144.03 (correct)

Kevin should print at least 1801 copies per year
