In determine the rate increase, we have the following formula:


\text{rate}=\frac{\text{amount added or increased}}{\text{original amount}}*100

Since the original amount is $27 and it is raised to $37, that means the amount added to the original amount is $10. ($37 minus $27 = $10.

So, we have:

amount added = $10

original amount = $27

Let's plug this in to the formula above.


\text{rate}=(10)/(27)*100\approx37.0

Therefore, the rate increase in percent in the original tuition's cost is 37.0%. An additional 37.0% has been added to the original cost.
