3.8: Software Sales A software company sells a package that retails for $99. Quantity discounts are given according to the following table: Quantity Discount 10-19 20% 20-49 30% 50-99 40% 100 or more 50% Write a program that asks the user to enter the number of packages purchased. The program should then display the amount of the discount (if any) and the total amount of the purchase after the discount. For instance, to calculate 20% of a value N, you can use the formula: (20 / 100.0) * N (or 0.2 * N).

(Statistics) This is the formula for the standard normal deviate, z, used in statistical applications: z=(X)/ X is a single value. refers to an average value. refers to a standard deviation. Using this formula, you need to write a program that calculates and displays the value of the standard normal deviate when X=85.3,=80,and=4. a. For this programming problem, how many outputs are required? b. How many inputs does this problem have? c. Determine a formula for converting input items into output items. d. Test the formula written for Exercise 7c, using the data given in the problem.
stoppingDistance = speed * (2.25 + speed / 21)Write a program which determines whether a vehicle’s tailgating distance is safe.The program should read in the speed of the vehicle and the vehicle’s tailgatingdistance. The program should then calculate the distance that would be required tostop the vehicle.If the stopping distance is less than the tailgating distance, your programshould print “No problem.” If the stopping distance equals the tailgatingdistance, your program should print “Minor wreck.” If the stopping distanceis greater than the tailgating distance, your program should print “Majorwreck!”

Computer Fundamentals and Programming 2 Write a program that determines a student’s grade. The program will accept 3 scores and computes the average score. Determine the grade based on the following rules: - If the average score is equal or greater than 90, the grade is A. - If the average score is greater than or equal to 70 and less than 90, the grade is B. - If the average score is greater than or equal to 50 and less than 70, the grade is C. - If the average score is less than 50, the grade is F.

Chapter 5. PC #2. Retail Price Calculator (page 312) Write a program that asks the user to enter an item’s wholesale cost and its markup percentage. It should then display the item’s retail price. For example: • If an item’s wholesale cost is 5.00 and its markup percentage is 100 percent, then the item’s retail price is 10.00. • If an item’s wholesale cost is 5.00 and its markup percentage is 50 percent, then the item’s retail price is 7.50. The program should have a method named calculateRetail that receives the wholesale cost and the markup percentage as arguments, and returns the retail price of the item.

code for this in C: In college, a student may get a grade of 1.0 (as the highest) to 5.0(lowest). Anyone who gets a Final Grade of at most 3.0 is considered a passing grade. Create a program that will ask the user to input a student's midterm grade and tentative final grade. After calculating the student's final grade using the formula below, main() will then call on DisplayStatus() to display if the student passed the subject or not. FG= MG+TFG/2
