Help with Beginner exercise.

Hi,

I have taken a summer school java programming course and am stuck on a problem. These are my first attempts so please be patient. Here is the question i am stuck on:

Find the net pay (n) for an employee who works 40 hours (h) at 5.50 per hour (w), has 3.00 (cpp) deducted for Canada Pension Plan and must pay 14% for tax (t). Tax is calculated on the gross pay after the insurance has been deducted. Display your answer in sentence form

What i have so far is this:

public class NetPay

/*

* Net Pay Program

*This program shows the net pay for an employee after tax and Canada Pension Plan deduction.

*/

{

public static void main(String[] args)

{

// variable declaration

int h;

double n, w, cpp;

// variable intialization

h = 40;

cpp = 3.0;

w = 5.50

// calculations

n = ((h * w) - cpp) * t;

// output

System.out.println("Net Pay Program");

System.out.println("The Net Pay is " + n);

}

}

Now the trouble is, i don't know how to assign t at the top as it is not a variable?? how do you do this? t is a fixed percent?

On a side note another one of my exercises were:

1.

Find the area of a 5.7 by 4.8 rectangle. Note: the mathematical formula for calculating the area of a rectangle is equal to length*width. Have your program display something similar to the following on the screen:

The width is 4.2

The length is 5.3

Note: For this program use memory location variables w, l, and a to represent width, length, and area. (A good habit is to use memory location variable names that represent the data you are storing.)

public class RectangleArea

/*

* Rectangle Area Program

*This program shows the area of a rectangle with width w and length l

*/

{

public static void main(String[] args)

{

// variable declaration

double l, w, a;

// variable intialization

l = 5.3;

w = 4.2;

// calculations

a = l * w;

// output

System.out.println("Rectangle Area Program");

System.out.println("The area is " + a);

}

}

Is this right?

Thanks for your help!
