Here, it should look like this.

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


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

    // add the calculateTaxes method here
    func calculateTaxes(percentage: Double) -> Double {
      return (self.amount * (percentage/100))
    }
    // it should accept only one parameter named 'percentage' of type Double

}
var item = Expense(description: "This is a description")
item.amount = 100

var taxes = item.calculateTaxes(7.5)
