Subtract $2.00 from $3.20 and that equals $1.20. Then, divide $1.20 by 2 and that gets you $0.60 and that's your answer.

When a problem like this is being done, it is easier to find the difference first and then break it down to find the answer. In this case when you subtract $3.20 and $2.00 you can figure out the difference in what she spent and then find the cost of each burger.
