The function that represents the simple interest formula is A(n)=P+(n-1)i*P, where n is a positive integer. (Option D)
Simple interest refers to the method of calculating the amount of interest charged on a sum at a given rate and for a given period of time. It is given by the formula:
SI = Pin
Where SI is the interest amount, P is the principal amount, i is the interest rate, and n is the number of period.
So, for n-1 years, the simple interest is:
SI = P(n-1)*i
The total amount charged is given by
A(n) = P + SI
A(n) = P + (n-1)i*P
Note: The question is incomplete. The complete question probably is: Select the function that represents the simple interest formula. A. A(n)=(n-1)(P*i)^n, where n is any real number. B. A(n)=n+(P-1)i*P, where n is a positive integer. C. A(n)=P(1+i)^n-1, where n is any real number. D. A(n)=P+(n-1)i*P, where n is a positive integer
