Explanation:
The stock that is bought by Rick Mendez: 5,000
Own money used to buy: 2,500
Borrowed money: 2,500
Interest on borrowed money : 30
Brokerage commissions: 300
The stock is sold after one month: 5,650
Now first calculate the net profit = Selling price of stock – cost price of stock – Interest on borrowing – commission
5,650-5,000-30-300=320
Now calculate the rate of return = Net profit / cost of stock
320/5,000=.06
.06 or 6%
