It is convenient to follow directions. Create a chart with activities as column headings. Since the data is divided according to gender, you would put gender on the row headings. Fill in the given numbers (black), and make the totals come out (blue).
The numbers in the row total column are exactly that: the total of the numbers in the row. (A spreadsheet can do the actual addition or subtraction for you.)
60 because If you replace y with 15 you will multiply and then get 60
For this question, the time given confuses me. I know the rate of return is just total return divided by divided by investment, Assuming that Matt received the $400 in dividends as cash payouts, and they weren't reinvested into buying shares of the stock, then his total return over two years was $500, Now, if Matt's dividends were reinvested into the stock - and if you have a 401(k) or IRA, that's what usually happens - then his ROI would have been only 6% because he only made a profit of $100 on an investment of $1500. Note: In the real world, in current market conditions, Matt probably would have got about a 5% return on a good stock, and Bella would have received about 0.05% on a savings account.
