Answer 19

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