# Problem 12
# Last month, Joe purchased some stock in Acme Software, Inc. Here are the
# details of the purchase:
# -The number of shares that Joe purchased was 2,000.
# -When Joe purchased the stock, he paid $40,000 per share.
# -Joe paid his stockbroker a commision that amounted to 3 percent of the amount
#  he paid for the stock.
# Two week later, Joe sold the stock. Here are the details of the sale:
# -The number of shares that Joe sold was 2000.
# -He sold the stock for $42.75 per share.
# -He paid his stockbroker another commission that amounted to 3 percent of the
#  amount he received for the stock
# Write a program that displays the following information:
# -The amount of money Joe paid for the stock.
# -The amount of commssion Joe paid his broker when he bought the stock.
# -The amount for which Joe sold the stock.
# -The amount of commission Joe paid his brokere when he sold the stock.
# -Display the amount of money that Joe had left when he sold the stock and paid
#  his broker (both times). If this amount is positive, then Joe made a profit.
#  If this amount is negative that Joe lost money.

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