Chapter 3, Problem 4PP
It is difficult to make a budget that spans several years, because prices are not stable. If your company needs 200 pencils per year, you cannot simply use this year's price as the cost of pencils two years from now. Because of inflation, the cost is likely to be higher than it is today. Write a

In various applications, you are often asked
to compute the mean and standard
deviation of data. The mean is simply the
average of the numbers. The standard
deviation is a statistic that tells you how
tightly all the various data are clustered
around the mean in a set of data. For
example, what is the average age of the
students in a class? How close are the ages?
If all the students are the same age, the
deviation is 0.
Write a program that prompts the user to
enter any number of values into a double
array, and then calculates and displays the
mean and standard deviations of these
numbers using the following formulas:

Stadium Seating There are three seating categories for a BC softball game. Class A seats cost $15, Class B seats cost $12, and Class C seats cost $9. Write a program that asks how many tickets for each class of seats were sold. Then display the total number of tickets sold, the amount of income generated from each class and the total ticket sales. Note: Use constants for the seat prices. Sample output: WELCOME TO THE BROWARD COLLEGE STADIUM!! Please enter the number of Class A seats sold: 100 Please enter the number of Class B seats sold: 200 Please enter the number of Class C seats sold: 150 ************************************************** Total number of tickets sold: 450 Income Generated:
Class A:$1500.00
Class B: $2400.00
Class C: $1350.00

- You found an exciting summer job for five weeks. It pays a per hour rate (which will be input to the program), and you will work the same number of hours each week (also input). Suppose that the total tax you pay on your summer job income is 14%. After paying the taxes, you spend 10% of your net (after tax) income to buy new clothes, accessories, and school supplies. After subtracting those items from your budget, you use 25% of the remaining money buy savings bonds. In addition, your parents buy additional savings bonds for you at 50% of the amount that you buy. Write a program that prompts the user to enter the pay rate per hour and the number of hours you will work each week.

- Write a program that computes how much a customer has to pay after purchasing two items. Make the lower-priced item half price. If the two items have identical prices, you can make one or the other half price. The price is calculated according to the following rules:• Buy one get one half off promotion: the lower price item is half price.• If the customer is club card member, additional 10% off.• Tax is added. Inputs to the program include:• Two items’ prices• Have club card or not (User enters ‘Y’ or ‘y’ for “yes”; ‘N’ or ‘n’ for “no”)• Tax rate (User enters the percentage as a number; for example, they enter8.25 if the tax rate is 8.25%) Program displays:• Base price - the price before the discounts and taxes• Price after discounts - the price after the buy one get one half off promotionand the member’s discount, if applicable• Total price – the amount of money the customer has to pay (after tax)printed with the precision of 2 decimal digits.
