Answer:
$5.50
Step-by-step explanation:
We can list out some values and continue this pattern until we reach 11 pages.
<em>2 pages costs $1</em>
<em>4 pages costs $2</em>
<em>6 pages costs $3</em>
<em>8 pages costs $4</em>
These are all points described by your graph. We will notice that every two pages costs $1, which also means that each additional page costs $0.50
This means that:
<em>10 pages costs $5</em>
and
<em>11 pages costs $5 + $0.50 =</em> $5.50
