Ok.

8. perl

x is the number of pages

9. kmullis6

So that's for part A?

10. perl

I am using the basic rate equation cost per page * number of pages = total cost

11. perl

cost per page of office scanner * no. pages > flat rate to rent scanner + cost per page of rented scanner

12. perl

$\Large .09x >70 +.02x$

13. kmullis6

Ok. Sorry, I'm confused. So what you had before was a mistake, and what is above is for A now?

14. perl

yes I am revising as I think about the problem

15. kmullis6

Oh ok

16. perl

THe english inequality should explain how I got the math part. Want to go over it one more time. just to be sure

17. kmullis6

18. kmullis6

I think I get it. Thank you

19. perl

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 $$\Large 70 + .02x < .09 x$$

20. perl

for part B you can solve the inequality for x

21. kmullis6

1,000

22. perl

correct :)

23. perl

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.

Thank you so much for all of your help! (: @perl
