The blue line, representing private colleges, is slightly above 60.000 at its end and the gray line is slightly above 20,000.
Considering it, we can come to the conclusion that the private college will be about 3 times more expensive at this time, since 60,000 is the same as 3 times 20,000.
Once this is certified, there's only one answer that fits what was observed:
<em>"It will be almost tiple the cost of a public four year college."</em>
