The compound interest formula is given by Tt A = P[1+- where A is the accumulated amount, after an initial investment of P dollars is invested for t years, at annual interest rate r, compounded n times per year. Use the formula above to determine how long it will take an initial investment of $5,250 to grow to $24,675, if the account earns 5.2% interest per year, compounded semi-annually. Round the solution to two decimal places. The account balance will reach $24,675 after years. Question Help: Video
