In this Ruby coding exercise, we're going to build out a pretty price method inside of Ruby and what that really means because that name is a little bit vague. What it means is that it's going to be a method that can take in two different numbers so it can take in whatever the gross cost is and then it's going to be able to take in a decimal extension.

In this Ruby coding exercise, we are asked to build out a get average method here in Ruby.
