Thread: Math Problem

Processing:

Declare a String object to hold the programmer’s name - FINISH
Declare three floating-point numbers and fill them from the Scanner input - FINISH
Add the floating-point numbers together to create a subtotal - FINISH
Calculate the tax for this subtotal, based on a tax rate of 9.25% - FINISH
Calculate the total amount, which is the sum of the tax amount and subtotal - HELP ( no error but it's giving me the wrong answer)

String firstNameString;
	float firstTax;
	float secondTax;
	float thirdTax;
	final double taxRate = 9.25;
 
 
 
	Scanner inputScanner = new Scanner(System.in);
 
	firstNameString = JOptionPane.showInputDialog("Enter your name");
	System.out.print("\nEnter your First Number: ");
	firstTax = inputScanner.nextFloat();
	System.out.print("\nEnter your Second Number: ");
	secondTax = inputScanner.nextFloat();
	System.out.print("\nEnter your Third Number: ");
	thirdTax = inputScanner.nextFloat();
 
	//Display our input values
	System.out.println("Name: " + firstNameString);
	System.out.println("Total of three numbers: " + (firstTax + secondTax + thirdTax));
	System.out.println("Tax " +(firstTax + secondTax + thirdTax) / taxRate);
	System.out.println("Subtotal Tax: "+firstTax + secondTax + thirdTax + (+firstTax + secondTax + thirdTax / taxRate));

Sample Data (could be used for testing):

If you input the following three values for your floating-point numbers:
50.99
75.95
53.95
The subtotal (3 numbers added) will be: 180.89
The tax will be: 16.73
The total amount including the tax will be: 197.62
(The number of your decimal places will be different)

first i want to get the answer of 9.25% of the total of 3 numbers
then i want to add that 9.25% of that number to the total or the 3 numbers

for example

Your First Number: 11.11
Your Second Number: 11.11
Your Third Number: 11.11
Total: 33.33
9.25% of 33.33 is: ?? ( i dont know how to do it)
9.25% of 33.33 + 33.33 = ?? ( same here )

System.out.println("Subtotal Tax: "+firstTax + secondTax + thirdTax...)

It prints these numbers next to each other, so if they're all 11.11 it'll print 11.1111.1111.11
if you'll write it this way:
System.out.println("Subtotal Tax: "+(firstTax + secondTax + thirdTax)...)
it'll print 33.33
