Enrique and Yolanda collected 500 pieces of candy on Halloween. They gave half of their candy to charity. Yolanda took 180 pieces of the candy and Enrique took the rest. Enrique told his mother he got 64% of the candy. What did Enrique do wrong in calculating his percentage?


He forgot how many pieces they started with.


He didn't account for the candy that was given away.


He counted Yolanda's candy as his own.


He multiplied incorrectly.
