Question

Jess uses her office scanner to scan pages at the rate of $0.09 per page. She decides to rent a scanner for $70 a year. The cost of scanning using the rented scanner is $0.02 per page.

Part A: Write an inequality that can be used to calculate the number of pages that Jess should scan in a year so that the amount she pays for the rented scanner is less than the office scanner. Define the variable used. (5 points)

Part B: How many pages should Jess scan in a year to justify renting the scanner? Show your work. (5 points)

Answer 1

O = 0.09x
R = 70 + 0.02x

O is office cost, R is rented cost and x is the number of pages.

to find the number of pages that justify, make O = R and solve for x.

0.09x = 70 + 0.02x

x = 1000
