report_totals.swift

let taxPercent = 
let pricesInCents = [1200, 800, 500]
let subtotal = pricesInCents.reduce(0, +)
let tax = subtotal * taxPercent / 100
let total = subtotal + tax
let message = "total_cents=\(total)"

print(message)

let taxPercent = 
let pricesInCents = [1200, 800, 500]
let subtotal = pricesInCents.reduce(0, +)
let tax = subtotal * taxPercent / 100
let total = subtotal + tax
let message = "total_cents=\(total)"

print(message)

let taxPercent = 
let pricesInCents = [1200, 800, 500]
let subtotal = pricesInCents.reduce(0, +)
let tax = subtotal * taxPercent / 100
let total = subtotal + tax
let message = "total_cents=\(total)"

print(message)
