R = interest rate per period as a percentage 2. t = number of periods Commonly, periods are years so R is the interest rate per year and t is the numbe...
The basic compound interest formula is: A = P(1 + r)t, where A is the accrued amount, P is the principal investment, r is the interest rate per period in decimal form, and t is the number of periods. If we change this formula to show that the accrued amount is twice the principal investment, P, then we have A = 2P. Rewriting the formula: 2P = P(1 +...
