Monthly Sales Tax
A retail company muse file a monthly sales tax report listing the sales for die month and the amount of sales tax collected. Write a
If the total amount collected is known and the total sales tax is 6 percent, the amount of product sales may be calculated as
where S is the product sales and T is the total income (product sales plus sales tax). The program should display a report similar to the following:
| Month: August 2016 | |
| Total Collected: | $26572.89 |

Interest Rates Savings accounts state an interest rate and a compounding period. If theamount deposited is P, the stated interest rate is r, and interest is compounded m timesper year, then the balance in the account after one year is P⋅(1+rm)m. For instance, if$1000 is deposited at 3% interest compounded quarterly (that is, 4 times per year), thenthe balance after one year is1000⋅(1+.034)4=1000⋅1.00754=$1,030.34.Interest rates with different compounding periods cannot be compared directly.The concept of APY (annual percentage yield) must be used to make the comparison. TheAPY for a stated interest rate r compounded m times per year is defined byAPY=(1+rm)m−1.(The APY is the simple interest rate that yields the same amount of interest after oneyear as the compounded annual rate of interest.) Write a program to compare interestrates offered by two different banks and determine the most favorable interest rate. SeeFig. 4.24.
Periodic compounding
The total accumulated value, including the principal sum P, is given by the formula:
where:
nt
A = P(1 + 1) "²
n
A is the final amount Accumulated Value
P is the original principal sum
r is the nominal annual interest rate
n is the compounding frequency
t is the overall length of time the interest is applied (expressed using the same time units as r, usually years).
Using the above formula write a program that will display the following table.
Principal-Value | Times-Interest-Compunded | Annual-Int-Rate | Term | Accumulated-Value
1000
6.00%

3.20%

A Charge Account Statement
Write a program to prepare the monthly charge account statement for a customer of CS CARD International, a credit card
company. The program should take as input the previous balance on the account and the total amount of additional charges
during the month. The program should then compute the interest for the month, the total new balance (the previous balance
plus additional charges plus interest), and the minimum payment due. Assume the interest is 0 if the previous balance was 0
but if the previous balance was greater than 0 the interest is 2% of the total owed (previous balance plus additional charges).
Assume the minimum payment is as follows:
new balance
for a new balance less than $50
$50.00
for a new balance between $50 and $300 (inclusive)
20% of the new balance
for a new balance over $300
So if the new balance is $38.00 then the person must pay the whole $38.00; if the balance is $128 then the person must pay
$50; if the balance is $350 the minimum…
