Answer 3

To calculate the overall percentage change in the scholarship, you can't simply add and subtract the percentages directly. Instead, you need to use the formula for successive percentage changes:

Overall Percentage Change = (100% + First Percentage Change) * (100% - Second Percentage Change) / 100% - 100%

First, let's calculate the first percentage change (increase of 20%):

First Percentage Change = 20%

Next, let's calculate the second percentage change (decrease of 15%):

Second Percentage Change = 15%

Now, plug these values into the formula:

Overall Percentage Change = (100% + 20%) * (100% - 15%) / 100% - 100% = 120% * 85% / 100% - 100% = 102% - 100% = 2%

So, the scholarship will increase by 2% after the initial 20% increase and 15% decrease.
