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

        init (description: String) {
         self.description = description
            }
      func calculateTaxes(percentage:Double) ->Double {
           return  self.amount * (percentage/100)

            }
       }

Create a variable named item and assign it an instance of Expense (remember to use the initializer with the description parameter. Enter any description you like). On the next line assign the amount property a value of 100.
