This is a simple subtraction problem, but since you are in Elementary School, I will help you out.
Subtract $4,190.67 by $3,655.11 (remember, the bigger number should come first)
4,190.67
-3,655.11
...56
When a small number is on top of a bigger number, borrow 1 number from the number next to it (in this case, 0 is smaller than 5, so you must borrow 1 number from 9, making it to 8), then add the small number by 10 (0+0=10)
Then we continue...
4,190.67
-3,655.11
35.56
Do the same thing with 4 and 1.
4,190.67
-3,655.11
535.56
Answer: $535.56
