Answer:
10
Step-by-step explanation:
This means that 12/(2x+1)=8/(x+4). Cross multiply to get 16x + 8 = 12x + 48. Subtract 12x + 8 from both sides to get 4x = 40, so x = 10.
Answer:
It is 6%
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%
