Add a method to the Expense struct that will calculate taxes based on a percentage passed to the method. In this task, add a method named calculateTaxes which accepts a parameter named 'percentage' of type Double and does not return anything. (In the next task we will add the calculations to the method). ???

struct.swift 
struct Expense {
    var description: String
    var amount: Double = 0.0

    init (description: String) {
        self.description = description
    }
      }

    func calculateTaxes() -> Double   
                return"" 
                }

   // add the calculateTaxes method here

You just need to add an empty function, taking one parameter and not returning anything. This way:

func calculateTaxes(percentage: Double) {
}

The next task will ask you to actually write the code within the method.
