To solve this problem, you need to calculate the percentage increase in tuition from last year to this year.

Here’s the step-by-step process:

1. Find the difference in tuition: $4362 - 3615 = 747$

2. Calculate the percentage increase: The formula for percentage increase is: $\text{Percentage Increase} = \left( \frac{\text{Difference}}{\text{Original Amount}} \right) \times 100$ Substituting the values: $\left( \frac{747}{3615} \right) \times 100 = 20.7\%$

The percent increase in tuition is 20.7%.
