Early one morning Sandy took out one-half of the coins from her coin bank, and in the evening she put in 20 coins. The next morning she took out one-third of the coins in the bank, and that evening she put in 4 coins. The next morning, she took out one-half the coins in the bank, leaving 15 coins. How many coins were in the bank to begin with?
