An investment of P dollars is deposited in a savings account that is compounded quarterly with an annual interest rate of r, where r is expressed as a decimal. The amount of money A in the account after t years is given by A = P (1 + r/4)4t. Use this equation to determine the time it takes for an investment of $10,000 to increase to$12,000 if it is placed in an account that is compounded quarterly with an annual interest rate of 1.6%. Round to the nearest tenth.
