Why am I still getting the wrong answer when I'm inputting the proper percentage?

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: "Hello")
    item.amount = 100

    var taxes = calculateTaxes(7.5)

Hello hello :) Your last sentence: "Call the method calculateTaxes on the variable item and assign the result to a new variable named taxes."

translates to something along the lines of: taxes = item.calculateTaxes(7.5)

It asks you to create a variable named taxes, so:

var taxes = item.calculateTaxes(7.5)
