You probably are fond of games. This quiz though is not that complicated. You are simply going to work with a point on a screen, and a circle on a screen as well. And let's consider them as the characters in the game. We are going to call both of these characters as Movable objects. Objects are said to be Movable if they can be moved around the screen. The following simple movements are allowed:

public void moveLeft(); // moves the x to the left by 1 unit

public void moveRight(); // moves the x to the right by 1 unit

public void moveUp(); // moves the y 1 unit upward

public void moveDown(); // moves the y 1 unit downward

public void display(); // prints all the info about

create a program that will accept a student name, student grade and will display the name and its equivalent grade.

A nested if is needed to validate the range of grade from 0 to 100 only. Inputted grade outside the given range is invalid input and there’s no grade equivalent. Your program should use nested if to validate the grade input and use the if-else statement to validate the grade options. Your program should have an input part and a display part. In the input part, you will be asked to input student name and student grade. For the output part, you have to display the student’s name and grade as shown in the sample output. The grading system is shown below.

Programming Problem 4: Caffeine Absorption

(Note: Programming Problem 4 draws directly on Chapter 6, Programming Project 1, page 285.)

Nutritional Associates of New Jersey stresses to their patients the effects of caffeine on the body. After caffeine is absorbed into the body, 13% is eliminated from the body each hour. Assume a person drinks an 8-ounce cup of brewed coffee containing 130 mg of caffeine, and the caffeine is absorbed immediately into the body. See Figure 6.77 in the Visual Basic text, and write a program to compute the following values: 

1. The number of hours required until 65 mg (one-half the original amount) remain in the body 
2. The amount of caffeine in the body 24 hours after the person drinks the coffee

Suppose the person drinks a cup of coffee at 7:00 a.m. and then drinks a cup of coffee at the end of each hour until 7:00 a.m. the next day. How much caffeine will be in the body at the end of the 24 hours?

Create a Python script which will compute the TOTAL Sales in a Grapes Store. The grapes is sold at 235.75 per kilo. 5% discount is given to customers that will buy 5 kilos and above. Compute also the CHANGE after the customer tendered their money. Format the display with two decimal digits.

Sample Output 1:

GRAPE STORE

No. of Kilos: 3

Total Price: 707.25

Discount: 0.00

Discounted Price: 707.25

CASH: 1000

Change: 292.75
