Question

Write a program in JavaScript using if-blocks that allows the user to input a taxable income value into a text box, and after clicking a button the tax is calculated and displayed in another text box.  Write a function to do the tax calculation.  The answer should be rounded to 2 decimal places.  Your program should calculate the correct tax no matter what the income range.  Use an IF-block to make this work.

Tax Table Program: Decision Blocks
Shown below is the 2001 Federal Income tax table for single taxpayers. This program requires using If-blocks, so study the
example programs in the notes on Decisions in order to get a good idea of how to complete the program.
The program should take an income value as input and calculate and display the tax due. For example, your program interface
might look something like this (you have some latitude as to the appearance).
Tax calculator
58321
Input your income
Calculate Tax
12657.03
Tax to be paid
Note the lack of dollar signs and commas in the numbers in the above display. The tax calculation is based on the following
table.
Taxable Income From
Up to but not including
Tax is
$27,050
15% of the income
$27,050
$65,550
$4,057.50 + (27.5% of the amount over $27,050)
$65,550
$136,750
$14,654.00 + (30.5% of the amount over $65,550)
$136,750
$297,350
$36,361.00 + (35.5% of the amount over $136,750)
$297,350 and up
$93,374.00 + (39.1% of the amount over $297,350)
For example, if a single person's income is $70,000, then the tax calculation for tax owed would be:
14654.00 +
(.305 *
(70000 - 65550)) = 16011.25
No dollar signs or commas should be used in the numbers of the above calculation.

Important. JavaScript numbers cannot have non-numeric characters in them and still be treated as a number. So although the
table above uses commas and dollar signs to display the number, JavaScript will treat something like $36,361.00 as text, not a
number. To do arithmetic any calculation or comparison using JavaScript needs to use raw numbers, like 36361.00.
Don't use commas or dollar signs in your program. Assuming the variable named income holds a number, then this will work:
if(income < 15000)
but this will not
if(income < $15,000)
If you want to format a number, do it just before it is displayed, after any comparisons or calculations have been performed.
Write a program using if-blocks that allows the user to input a taxable income value into a text box, and after clicking a button
the tax is calculated and displayed in another text box. Write a function to do the tax calculation. The answer should be
rounded to 2 decimal places. Your program should calculate the correct tax no matter what the income range. Use an IF-block
to make this work.
When finished, attach the file to an email and send it to me. Also, please copy and paste the source code into the body of the
email. If you have trouble with this before the due date, send it to me and I will be glad to make suggestions (but don't wait
until late Sunday night). As a hint, look back at the program that calculates letter grades (gradeCalculator) in the examples for
the week discussing decisions.
In newer versions of JavaScript you can round a number to 2 decimal places using the toFixed() method. If the variable tax
holds an unrounded number, you can round to 2 decimal places with the following line:
tax =
tax.toFixed (2)
where the 2 in parenthesis is the number of decimal places to be rounded to. JavaScript is case sensitive, so if you use
toFixed(), make sure to spell it correctly.
When everything works, attach the html document to and email, paste the source code into the body of the email, and send it
to me.
