You invest $1,500 into a "hot stock" through the Robin Hood app. The stock does well in the first quarter and in the second quarter. At the end of the second quarter, the stock's value is $2,250 and you buy another $1,000 worth of shares. At the end of the year, your shares are now worth $3,300. What is your money-weighted return? State your answer as a raw number, not in decimal form (i.e. 13.21 not 0.1321) with two decimal places.
