Your answer is A. I have attached a photo of an explanation
Money makes for nice decimal examples.
If you had $1.50, and you wanted to split it among three people, you would have :
1.50 divided by 3 (which would be $0.50 each)
By 30%
original=100%
100%+30%=130%
find 130% of 288846
1.30 times 288846=375499.8
