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

}

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

Thanks Jhoan!

I tried this, but got the following error:

swift_lint.swift:16:1: error: expected declaration item.amount = 100 ^

What am I doing wrong?
