The answer will be $68 and Here's Why:
Samantha received $59 for her birthday. That will be the base of the equation. She spent $25 on a charm bracelet so that will be the number being subtracted.
$59 - $25 = $34
We also know that he brother has twice as much money as she does. So that means he has 2x more money than her.
So: $34 x 2 = $68.
So here brother has $68 more than her.
