Suppose that a certain fortunate person has a net worth of $77.0 billion ($). If her stock has a good year and gains $3.20 billion () in value, what is her new net worth? Express your answer to three significant figures. Suppose that this individual now decides to give one-eighth of a percent (0.125 ) of her new net worth to charity. How many dollars are given to charity? The answer is not 10.0025 or 12.5. I have been working at this problem and just need to figure out how do this for future reference.
