Final answer:
Rui Feng has to pay the bank a total amount of $53,760 at the end of 2 years.
Step-by-step explanation:
To calculate the total amount of money Rui Feng has to pay the bank at the end of 2 years, we can use the formula for simple interest:
Interest = Principal * Rate * Time
Principal = $48,000
Rate = 6% per annum = 6/100 = 0.06
Time = 2 years
Plugging in the values into the formula:
Interest = $48,000 * 0.06 * 2 = $5,760
The total amount of money Rui Feng has to pay the bank at the end of 2 years is the sum of the principal and the interest:
Total amount = Principal + Interest = $48,000 + $5,760 = $53,760
