Answer:
9.6%
Explanation:
To find her rate of return we have to first determine the total gains on her investment, from which the total cost will be subtracted and then the rate of return can be calculated.
Inflows
Dividend = $0.5*300 shares = $150
Sales........=$33.75*300 shares = $10,125
Total inflow...................................= $10,275
Outflow
Purchase of shares = $31.25*300 shares = $9,375
Returns = Inflow - Outflow = $10,275 - $9,375 = $900
Rate of returns = 900/9,375 = 0.096 or 9.6%
