Hello : The first part of the challenge is as follows.
```swift
struct Expense {
    var description: String
    var amount: Double = 0.0
init (description: String) {
    self.description = description
}

func calculateTaxes(percentage: Double) {
}
// it should accept only one parameter named 'percentage' of type Double
}
```
the second part 
```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)
}
// it should accept only one parameter named 'percentage' of type Double
}
```
The third part 
```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: "House")
item.amount = 100
````
and the final part 
```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: "House")
item.amount = 100
var taxes = item.calculateTaxes(7.5)
