Need help in Visual C# 2008

Question

I'm very new to C# 

I had to write a program that inputs the number of hours worked by 5 people and outputs the amount each person gets paid. 

Everyone gets paid $10 an hour, and if that person works over time I have to include their time and a half pay as well ($15). 

I know how to get the regular pay, but how would I calculate the over time pay? 

Thank you in advance.
