You used the math from the problems in the last section. This is asking how much was made in the last year. So you need to subtract what she had a year ago from what she has now to get the answer and you missed that step, which is exceptionally frustrating because I am sick of these idiotic problems being in my suggested list and it makes it hard to clear them out so I can get to just seeing new things, like calculus.
