**Math Riddle: ** David is throwing Robert a surprise birthday party but he has to stay within his budget. He spent half of his money plus $2.00 on the cake. Half of what he had left plus $2.00 was spent on balloons and streamers. Then he spent half of what he had left plus $1.00 on candy. Now he is out of money, how much did he start with?

**Answer: **The correct answer is best fathomed working in reverse, the last part David spent a portion of what was left in addition to $1.00 on candy and afterward was out of cash.

That implies he more likely than not burned through $2.00 on Candy as $1.00 was half of what he had utilized a similar rationale in reverse: $2.00 on candy $6.00 on Balloons and Streamers $12.00 on the cake Total of $20.00.
