Hump Day Brain Teaser......

Brain Teaser #180

George makes the following proposition to Mike:

"I will let you flip a coin 20 times. Each time the coin lands
on heads, I will give you $2.00. However, each time the coin
lands on tails, you must give me $3.00."

Mike flips the coin 20 times and the end result is that no money
is to change hands.

How many times did the coin land on heads?
