So in doing the math.
The difference between a McDouble and a double cheeseburger is a slice of cheese, for which they charge you twenty nine cents.
The difference between a cheeseburger and a McDouble is a hamburger patty, for which they charge a penny.
And the difference between a cheeseburger and a double cheeseburger, one patty and one slice of cheese, is thirty cents.
It makes perfect sense.
Patty - 0.01
Slice Cheese - 0.29
Both together - 0.30
It works.
