how to assign the value in struct

struct Expense { var description: String
var amount: Double = 0.0
init (description: String) { self.description = description var item = "some Values" self.amount = 100

}


// add the calculateTaxes method here
// it should accept only one parameter named 'percentage' of type Double
func calculateTaxes (percentage : Double) -> Double {

return amount * (percentage/100)

}

}

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

    init (description: String) {
        self.description = description
        var item = "some Values"
        self.amount = 100

    }


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

    }

}

Hi Mohammad Usman !

Challenge Task 4 of 4 asks "We need to figure out the tax amount when the tax percentage is 7.5 percent. Call the method calculateTaxes on the variable item and assign the result to a new variable named taxes."

You can do this by assigning item.calculateTaxes(7.5) to the variable taxes like this: var taxes = item.calculateTaxes(7.5)

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

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

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

}

var item = Expense(description: "My description")
item.amount = 100

var taxes = item.calculateTaxes(7.5)
