Question

Given the formula for compound interest A = P(1 + $$r/n)^{nt}$$, isolate r symbolically (write r in terms of A, P, n, and t).

Accepted Answer

r = n[(A / $$P)^{1 / (nt)} - 1$$]

Answer

r = (A / $$P)^{n / t} - n$$

Answer

r = (A - P) / (Pnt)

Answer

r = (A / $$P)^{nt} - 1$$

Given the formula for compound interest A = P(1 + r/n)nt, isolate r symbolically (write r in terms of A, P, n, and t).
