Answer :
Answer:
The answer is "A"
Explanation:
Cumulative interests are counted by one plus the annual interest rate adjusted to the cumulative periods of less than one. The first principal sum is determined by one. The cumulative sum of the initial loan is then deducted from the calculation.
Formula:
[tex]A= \ p (1+ \frac{r}{n})^{nt} \\\\\ Where,\\ \\ A = \ annual \ interest\\P = \ principal\\t= time\\r= rate[/tex]
That's why we apply the above formula to calculate the annual interest rate.
Answer: 1. (n) 2. (r)
The number of times that interest is compounded per year is represented by the variable (n), while the annual interest rate is represented represented by (r).
Explanation: That is the compound interest expression.
