"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."
Someone please help we
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: "Car")
item.amount = 100

var taxes = item.calculateTaxes(7.5)
How does this work?
You created an instance of the Expenses struct and assigned it to the variable item before. Now you have access to all methods of this struct via the item variable.
