Covered Calls

How is the break-even price of a covered call calculated?

What happens if your covered call is in the money at expiration?

You purchase shares of XYZ at $20.00 and sell 1 $22.50 call for $0.50, what is your maximum profit potential?

We purchase shares of ABC at $65.00 and sell 1 $67.50 call option for $1.50, at expiration ABC trades at $64.00. Did we make money?

Why would you want to sell a covered call?
