Write method in java

2. We have that I gross 144 of something, 1 dozen 12 of something, and 1 of something is just one of something. Wally's Widgets sells a gross of widgets at the cost of $80, a dozen widgets at a cost of S10, and single widgets less than a dozen at the cost of $1 per widget. You are to write the code for a method that returns the bill for a given number of widgets as per the above scheme, one that breaks a number down into grosses, dozens and units to find the (cheapest) bill Wally will make for a given number. I have provided 10 sample runs on the Question 2 sheet with different order values as inputs. You need not include the breakdown display in your code (as I have), just simply write the code that returns the bill Wally will write you. The call to the code of the method you must write is shown in bold
