Exercises

**1. Write a program to help you budget your fuel
expenses. Enter a value for the number of miles you drive in one month, and
another for the miles per gallon (MPG) your car gets. Assuming gas costs $3.35
a gallon, calculate your monthly fuel costs.**

Enter monthly mileage: __1500__

Enter MPG: __30__

You spend $167.50 a month on gas

**2. Write a program that accepts
two real numbers and prints out their sum, difference, product and quotient to
2 decimal places.**

Enter a number: __4.8__

Enter a number: __1.2__

Sum = 6.00

Difference = 3.60

Product=5.76

Quotient=4.00

**3. a) Write a program that
reads the price of a hamburger and the number of hamburgers bought. Print out
the cost, in dollars and cents, of the purchased hamburgers. Use appropriate
variable names to represent the values assigned to the variables:**

Enter price of hamburgers: __0.59__

Enter number of hamburgers: __10__

The cost of hamburgers is $5.90

**b) Edit the program
to include calculation of a 6% sales tax:**

Enter price of hamburgers: __0.59__

Enter number of hamburgers: __10__

The cost of hamburgers is $5.90

Sales tax is $0.35

Total cost of hamburgers is $6.25

**4. Write a program to produce the following table using
integers:**

Enter an integer: __11__

Enter an integer: __3__

11 + 3 = 14

11 - 3 = 8

11 * 3 = 33

11 div 3 = 3

11 mod 3 = 2

**5. Write a program that allows a person to enter
his or her weight in pounds and height in inches and then calculates the ratio
of pounds per inch:**

Enter height in inches: __74__

Enter weight in pounds: __202__

Pounds per inch = 2.73

**6. a) Parking
tickets at the **

**Write a
program which uses a constant named Fine to calculate how much money you owe
the parking department:**

** **

**(Hint: To put a constant into a program type ****Const Fine=22.75 at
the top of the code window.)**

** **

How many tickets do you have? __8__

You owe $ 182.00

**b) **

How many tickets do you have? __8__

You owe $ 220.40

It will take 14.69 weeks to pay your fine.

**7. a) The area of a
triangle is equal to one half the base times the height. Write a program that
reads the base and height of a triangle in centimeters and then writes the
area using formatted output:**

Enter the base in centimeters: __21__

Enter the height in centimeters:
__43__

The area is 451.50 square centimeters.

**b) There
are 2.54 centimeters in an inch. Expand your program to also give the area in
square inches. (Remember to convert centimeters to inches before finding the
area.)**

** **

Enter the base in centimeters: __21__

Enter the height in centimeters: __43__

The area is 451.50 square centimeters

or 69.98 square inches.

**8. Sheila runs a pool service that charges by the
square foot of pool serviced. Write a program that allows the user to enter the
length and width of the pool and calculates the total cost. Use a constant to
represent the cost per square foot, $0.17:**

Enter the length of the pool: __25__

Enter the width of pool: __15__

The area to be serviced is 375.00 square feet. This job will cost $63.75

**9.** **a****)
Pizza contains 355 calories per slice. Jogging burns off 240 calories**

**per****
hour. Write a program to calculate how long, in hours and minutes,**

**you****
would have to jog to burn off the pizza that you eat:**

** **

How many slices of pizza? __3__

You will have to jog 4.44 hours

b) Sushi only contains 120 calories per piece. Edit your program so that its output looks like this:

How many pieces of sushi? __3__

You will have to jog 1.50 hours

**10. a) Amy's Garden Emporium must
ship an order of flower pots to **

How many flower pots to be
shipped? __26__

You will need: 6 big boxes

2 small boxes

**b) Amy's
head shipping clerk has ordered another size box that can hold 9 pots. Edit
your program to use all three sizes of boxes:**

How many flower pots to be
shipped? __88__

You will need: 9 large boxes

1 big boxes

3 small boxes

**11.****
Write a program to print the coins necessary to return change to a
customer after a purchase. The change can be made up of the following coins:
quarters, dimes, nickels and pennies. Your may assume that the amount of change
is less than $1.00. Your program should use the minimum number of coins needed.
**

**
(Hint: You Need Div and Mod)**

** **

Enter amount of change in cents: __69__

Change:

Quarters: 2

Dimes: 1

Nickels: 1

Pennies: 4

**12.
Professional athletes have succeeded in making staggering sums of money through
careful negotiations. Of course, the real winner is the Internal Revenue
Service, which does not negotiate at all. Write a program which asks for a
player's earnings and then prints the takehome pay
and taxes assuming the tax rate for that income bracket is 44%:**

What are the player's earnings? __150000.0
__

The player keeps $84000.00

The player pays $66000.00 in taxes.
