PROBLEM: You have been hired by the local donut shop to help compute the total cost of customer orders. Donuts cost $0.75 each and donut holes cost $0.25 each. Once the user has entered how many of each item will be purchased, a subtotal should be computed. If this subtotal is $10 or more, a 10% discount is applied to the subtotal. A tax is then calculated by multiplying the subtotal by 8.5% (or 0.085). Finally, the total owed is computed by adding the subtotal and the tax. The three amounts (subtotal, tax, and total) should all be displayed using 2 decimal places each.

You may only submit your solution one time so read the directions carefully before you submit to Canvas. This final exam must be created using a single Word document.

PART #1 (20 points):

• Create a step-by-step algorithm that solves the problem described above. List the five essential properties of an algorithm and explain how your algorithm meets each of these properties.
• Write a Python program to solve the problem. You must include at least 4 lines of comments as you did in previous Python activities this semester.

PART #2 (20 points):

• Using Draw.IO, create a flowchart to model the solution to the problem.
• Be sure to use the correct shapes as previously directed earlier in the semester.
• You must include a text box in your flowchart with your name, etc. as done in previous flowchart activities this semester.
• Export your flowchart as a PNG image.
• Using App Inventor, create an app that solves the problem.
• Use a 2×2 table to accept the user inputs. Have a button that will compute the total. Use a 3×2 table to display the three outputs along with their labels.
• You must include your full name in the title of your app.
• Notice that your email address shows up in the top right corner of App Inventor. This must be visible when doing the screen captures.
• Create a list of the ten most useful things you learned from CS135 this semester. These things may have been learned from the book, activities, quizzes, discussions, videos, etc.
• For each thing listed, briefly describe why you find it useful.
