We need to develop an inequality that would calculate the minimum number of pages that can be faxed for the total amount of $6.10 given that the first page was charged $1.70 and $0.55 for the subsequent pages.
Let x represents the subsequent pages, such that the inequality is shown below:
$6.10 > $0.55X + $1.70.
