x is the number of pages

  • kmullis6
So that's for part A?
perl
  • perl
I am using the basic rate equation `cost per page * number of pages = total cost`
perl
  • perl
cost per page of office scanner * no. pages > flat rate to rent scanner + cost per page of rented scanner

We want \[ \Large \rm rented ~ scanner ~ cost < office ~scanner ~ cost \]\[\Large \rm rental ~cost + \frac{cost}{page }\cdot \# pages < \frac{cost}{ page} \cdot \# pages \]\[ \Large \rm 70 +\frac{$0.02}{1 page } \cdot x ~pages <\frac{$0.09}{1 page} \cdot x~pages \\~ \] Finally we have $$ \Large 70 + .02x < .09 x $$
perl

for part B you can solve the inequality for x

Edit If she scans more than a 1000 pages in a year, she will save money using the rented scanner. if she scans less than a 1000 pages a year she will save money not renting and using the office equipment.
