JamEx Limited requires a program to calculate and print the commission received by a salesperson. The program should process an undetermined number of salespersons and appropriately terminate by a predefined input. The commission rate is based on two factors, the amount of sales and the class to which a salesperson belongs. The input will be the salesperson number, sales amount and class. The commission rate will be based on the following criteria:

Class=1

If sales is equal to or less than $1000, the rate is 6 percent.

If sales is greater than $1000 but less than $2000, the rate is 7 percent.

If the sales is $2000 or greater, the rate is 10 percent.


Class=2

If the sales is less than $1000, the rate is 4 percent.

If the sales is $1000 or greater, the rate is 6 percent.


Class=3

The rate is 4.5 percent for all sales amount


Class=any other value

A sinusoidal wave travelling in the positive x-direction has a wavelength of 0.4 m, an amplitude of 20 cm, and a period of 4 seconds. The transverse position of an element of the medium at x = 0 and t = 0 is y = 10 cm, and the element is moving downward. The expression of the wave function describing this wave is:
