write a javascript program to

Write a JavaScript program to solve the following problem: A company pays its salespeople on a commission basis. The salespeople receive $200 per week plus 9% of their gross sales for that week. For example, a salesperson who grosses $5000 in sales in a week receives $200 plus 9% of $5000, or a total of $650. Your program should obtain the gross sales for each employee through an XHTML form and determines how many of the salespeople earned salaries in each of the following ranges (assume that each salesperson’s salary is truncated to an integer amount): 

Ø $200 – 299

Ø $300 – 399

Ø $400 – 499

Ø $500 – 599

Ø $600 – 699

Ø $700 – 799

Ø $800 – 899

Ø $900 – 999

Ø $1000 and over
