Add a Double as a return type to the calculateTaxes method and within the method return the following expression:

(self.amount * (percentage / 100))

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

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

}

Hi Stanila,

Two issues:

  1. Your function definition needs to include a return type (you need a ->)

  2. You are returning the String "(self.amount * (percentage/100))". If you drop the quotes, you should be in business.

It should look like this =

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)) }

}
