Don't know what to do


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

    func calculateTaxes() -> Double {
    var percentage: Double

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

    // add the calculateTaxes method here
    // it should accept only one parameter named 'percentage' of type Double

Hi there,

So you're required to add a function that's called calculateTaxes that takes a Double as a parameter called percentage and returns nothing:

func calculateTaxes(percentage: Double) {


That is the method skeleton for that. The next parts of the challenge ill develop it further from there.

Hope that helps!
