Yeah I'm stuck on this struct

"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."

struct.swift 
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))
    }
}

var item = Expense(description: "Rent")
item.amount = 100
var taxes: 7.5
item.calculateTaxes(percentage: 7.5)

Hello,

Try 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))
    }
}

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

var taxes = item.calculateTaxes(7.5)
