Answer:
Julie has $11.51 left.
Explanation:
We know that Julie has $20. She spent $1.99 on package of trading cards and $6.50 for lunch. When added this is equal to $8.49.
Now we have to figure out how much she has left by subtracting $20 from $8.49 and we get $11.51. Therefore, $11.51 is our answer.
