The Employee work every day in different times, and he can start and stop to
job any time. for example:

In the date 01-Jul-2002 he started at 08:00 am and stop at 11:30 am, so he
worked 03:30.
In the date 02-Jul-2002 he started at 08:30 am and stop at 11:45 am, so he
worked 03:15.
In the date 03-Jul-2002 he started at 08:15 am and stop at 12:00 pm, so he
worked 03:45.

I want to pay for him job

Total hours worked: 10:30
Price by hour: \$ 50,00
Amount: \$ 525,00
