Emily uses her college photocopier machine to photocopy at the rate of $0.08 per page. She 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 Emily should photocopy in a year so that the amount she pays for the rented machine is less than the college machine. Define the variable used.

Part B: How many pages should Emily print in a year to justify renting the photocopier? Show your work.

Answer 1

Well say b is equal to the number of pages she copies. Using the photocopierr at the college would cost 0.08b and using the rented photocopier would cost 0.03b+90. The total cost of the using the rented photocopier must be less than the total cost of using the college copier. Thus 0.03b+90<0.08b

Answer 2

Solving for b: 90<0.05b
b=1800 copies

Answer 3

sorry 1800>b

Answer 4

sorry 1800<b

Answer 5

thank you
