  8. # Last month, Joe purchased some stock in Acme Software, Inc. Here are the

  17. # -He paid his stockbroker another commission that amounted to 3 percent of the
  18. #  amount he received for the stock

  49. # Problem 14
  50. # When a bank account pays compound interest, it pays interest not only on the
  51. # prinicipal amount that was deposited in the account, but also on the interest
  52. # that has accumulated over time. Suppose you want to deposit some money into a
  53. # savings account, and let the account earn compound interest for a certain
  54. # number of years. The formula for calculating the balance of the account after
  55. # a specified number of years is:
  56. # A=P(1+rn)nt
  57. # The terms in the formula are:
  58. # - A is the amount of money in the account after the specified number of years.
  59. # - P is the principal amount that was originally deposited into the account.
  60. # - r is the annual interest rate.
  61. # - n is the number of times per year that the interest is compounded.
  62. # - t is the specified number of years.
  63. # Write a program that makes the calculation for you. The program should ask the
  64. # user to input the following:
  65. # - The amount of principal originally deposited into the account.
  66. # - The annual interest rate paid by the account.
  67. # - The number of times per year that the interest is compounded (For example,
  68. # if interest is compounded monthly, enter 12. If interest is compounded
  69. # quarterly, enter 4.)
  70. # - The number of years the account will be left to earn interest.
  71. # Once the input data has been entered, the program should calculate and display
  72. # the amount of money that will be in the account after the specified number of
  73. # years.
