Help??!

Write a MATLAB program that computes the amount of income tax a person
needs to pay according to the following table:

Salary Range ($)         Base Tax ($)    Percentage of Excess
0.00 – 14,999.99          0.00                    15
15,000.00 – 29,999.99     2,250.00                18
30,000.00 – 49,999.99     5,400.00                22
50,000.00 – 79,999.99     11,000.00               27
80,000.00 – 149,999.99    21,600.00               33
>= 150,000.00             32,000.00               40

For example, if a person’s salary is $2,000.00, the income tax the person needs to pay is
$2,250.00 (base tax for the second range) plus 18% of the excess salary over $15,000.00 (that
is, 18% of $5,000). Therefore, the total tax due is $2,250.00 plus $900.00, which is
$3,150.00.
Your program should first prompt the user to input a salary amount (with the prompt of
“Please enter the salary amount: ”), then based on the amount and the above
table calculate the total amount of income tax. Your program should output to the command
window the total amount of tax as follows:
The total tax due is:
x
where x is the calculated total amount of tax with two digits after the decimal point. For
example, if the calculated amount is $3,150, the value should be displayed as 3150.00. If the
salary amount inputted by the user is negative, your program should output to the command
window:
invalid input
