you added 13 songs.
Prize money for first caller = $100
Amount added after every incorrect answer = $50
When 10th caller gives answer correctly, this means all the previous 9 callers gave incorrect answers.
Prize money for 10th caller = $100 + amount added for 9 incorrect answers
= $100 + 9 * ($50)
= $100 + $450
= $550
Hence, Prize money for 10th caller = $550
