Need assistance with Bonus Rate program

[tjaduffy]

I realllly need help with a program. I am not even sure where to start and what exactly to do!

JM Sales employs 10 salespeople. The sales made by the salespeople during the months of January, February, and March in the chart below. Stores the sales amount in a two dimensional array. The sales manager wants an application that allows him to enter the current bonus rate. The program should display each salesperson's number (1 through 10), total sales amount, and total bonus amount. It also should display the total bonus paid to all salespeople. Display the bonus amounts with two decimal places. Test using 10%.
Code:
Salesperson January February March
----------- ------- -------- -------
1 2400 3500 2000
2 1500 7000 1000
3 600 450 2100
4 790 240 500
5 1000 1000 1000
6 6300 7000 8000
7 1300 450 700
8 2700 5500 6000
9 4700 4800 4900
10 1200 1300 400

Thank you!!
