Adding Park Tickets from 3 to 4 days

[kaismahma]

Does anyone know off hand how much it would cost to add an additional park day to our 3 day park tickets. I know if we had 4 days in the park already purchased it would only be like $10 each. We ended up getting later flights our last day so I was thinking about adding them if it isn't too expensive.

According to the WDW ticket site a 3 day adult ticket is $275 and $305 for a 4 day, so $30.
