$20.00. This one is best solved working backwards, the last part David spent half of what was left plus $1.00 on candy and then was out of money. That means he must have spent $2.00 on Candy as $1.00 was half of what he had using the same logic backwards; $2.00 on candy $6.00 on Balloons and Streamers $12.00 on the cake. Total of $20.00.
