According to the given formula, the amount of money generated for a year at 5% interest, compounded monthly, is
1,000(1+)12 , whereas the amount of money generated at 3% interest, compounded monthly, is
1,000(1+)12. Therefore, the difference between these two amounts,
, shows how much additional money is generated at an interest rate of 5% than at an interest rate of 3%.
Choices A, B, and C are incorrect and may be the result of misinterpreting the given formula. For example, the expression in choice C gives how many times as much money, not how much additional money, is generated at an interest rate of 5% than at an interest rate of 3%.
