Answer to Section 7.13 Write a JavaScript Program for the following problem.

A large company pays its salespeople on a commission basis. The salespeople receive $200 per week, plus 9 percent of their gross sales for that week. For example, a salesperson who sells $5000 worth of merchandise in a week receives $200 plus 9 percent of $5000, or a total of $650. You have been supplied with a list of the items sold by each salesperson. The values of these items are as follows:

Item	Value
1	23.99
2	129.75
3	99.95
4	350.89

Develop a program that inputs one salesperson’s items sold for last week, calculates the salesperson’s earnings and outputs XHTML text that displays the salesperson’s earnings.
