Math Problem Statement
Following previous question: If the bank offers compound monthly interest calculation, calculate the net first month interest ($)? (Notes: Use 4 digits after decimal point)
Solution
To calculate the net first month's interest when the bank offers compound monthly interest, we need the following formula for compound interest:
Where:
- is the amount after interest.
- is the principal amount (initial deposit).
- is the annual interest rate (in decimal).
- is the number of times interest is compounded per year.
- is the time the money is invested or borrowed for, in years.
To find the first month's interest, we will calculate the difference between the amount after 1 month and the initial principal:
Assuming:
- is the principal amount.
- is the annual interest rate.
- (since interest is compounded monthly).
- years (since we are calculating for one month).
Please provide the principal amount and the annual interest rate , so I can complete the calculation.
