Using the formula V=Pert, where V is the value of the account in t years, P is the principal initially invested, e is the base of a natural logarithm, and r is the rate of interest, determine the amount of money, to the nearest cent, in the account after 16 years.Answer:
Q. A person places $427 in an investment account earning an annual rate of 3.7%, compounded continuously. Using the formula V=Pert, where V is the value of the account in t years, P is the principal initially invested, e is the base of a natural logarithm, and r is the rate of interest, determine the amount of money, to the nearest cent, in the account after 16 years.Answer:
Identify Given Values: Identify the given values from the problem.Principal P = $427Rate of interest r = 3.7% or 0.037 (as a decimal)Time t = 16 yearsWe will use the formula for continuous compounding: V=Pert
Substitute into Formula: Substitute the given values into the formula. V=427×e(0.037×16)
Calculate Exponent: Calculate the exponent part of the formula. 0.037×16=0.592
Calculate e Value: Calculate e raised to the power of the result from Step 3.e0.592 (Use a calculator for this step)
Multiply Principal: Multiply the principal by the result from Step 4.Assuming e0.592≈1.808 (using a calculator)V=427×1.808
Perform Multiplication: Perform the multiplication to find the final value. V≈427×1.808≈772.216
Round Final Value: Round the final value to the nearest cent. V≈$772.22
