There are 3 numbers given. Make sense of it, step by step. $3600, 25% and 30%. Don't kancheong! Try to draw out and it will be clearer.
The sign % means "out of a 100", so usually such questions require you to do simple math by subtracting from 100 or adding to a 100, then multiply by the original number.
