To find the percentage increase, we first need to calculate the amount of increase:

Amount of increase = New price - Old price
Amount of increase = $2.55 - $2.40
Amount of increase = $0.15

To find the percentage increase, we divide the amount of increase by the old price and multiply by 100:

Percentage increase = (Amount of increase / Old price) x 100
Percentage increase = ($0.15 / $2.40) x 100
Percentage increase = 6.25%

Therefore, the percentage increase is 6.25%. Rounded to the nearest tenth of a percent, it is 6.3%.
