Due Tuesday, October 30 at 9:20am on Canvas

Assignment 9.1: Making a Receipt (10 pts)
• Let's write a program to create a receipt.
• Open a new project in Eclipse called Cookies and create a new class called Cookies.java.
• This program will simulate an online cookie business and print out a receipt to the customer for their order.
• The program should follow the exact formatting shown below, including spacing and indentation.
• Hint: Remember "\t"?
• Note that you will need to print out exactly 2 decimal places for the dollar values.
• When you are finished, submit your program.

Allow me to assist you with your order.

We sell the following flavors:
Coffee Chai Cookies -- \$2.05 each

You Ordered the Following:
Mocha Cookies: 3 @ \$1.95 each...            \$5.85
Cocoa Cookies: 2 @ \$2.15 each...            \$4.30
Coffee Chai Cookies: 5 @ \$2.05 each...      \$10.25
Java Cookies: 1 @ \$1.85 each...             \$1.85

Total:                                      \$22.25

• Academic grades in the US are traditionally given as letter grades: A, B, C, D, and F. We need to translate these letter grades into number to calclulate a grade point average (GPA).
• Write a program that converts a letter grade into it's numerical value using the following conversion table.
A 4.00
A- 3.67
B+ 3.33
B 3.00
B- 2.67
C+ 2.33
C 2.00
C- 1.67
D+ 1.33
D 1.00
D- 0.67
F 0.00
• In a class file named LetterGrade.java, ask the user for a letter grade of A, B, C, D, or F, possibly followed by a + or -, and no other input as shown in the Example Run.
• Convert the letter grade into the numerical equivalent shown above.

Notice that the highest number is 4.0 and that there are no F+ or F- grades. Make sure that the highest grade number is 4.0 and that F+, F and F- are assigned 0.0 values.

• Display the output using the default formatting and precision for the numbers -- do NOT add any numerical formatting statements to the code.
• Sample Output: The input prompts and outputs of the program must look like the following for full credit, including the same order of input and wording of the output. For the input shown you must get the same output. However, the output must change properly if the inputs are different.
```Enter a letter grade: B-
The numeric value is 2.67
```
```Enter a letter grade: A+
The numeric value is 4.0
```
```Enter a letter grade: F-
The numeric value is 0.0
```

In the above three example runs, the user entered "B-", "A+" and "F-" (without the quotes) as the letter grades to convert.

• After displaying the output, exit the program.
• Submit your program when you are finished.

Assignment 9.3: What's Your Sign? (10 pts)

• For this assignment, let's write an astrology program.
• Welcome the user (see sample output below)
• Prompt the user to enter a numerical value (1-12) for the month of his/her birth (see sample output)
• Prompt the user to enter a numerical value (1-31) for the day of his/her birth (see sample output)
• Using the chart below for the astrological signs, determine the user's sign based on his or her input.
• Expect to need to use if, else if and else statements.
• Expect to use logical operators (&&, ||).
• Submit your source code in a file called Sign.java to Canvas when finished
