Did anyone complete the “Remaining Pints” challenge?

Here is how i achieved

const val TAVERN_NAME = “Taernyl’s Folly”
var playerGold = 10
var playerSilver = 10
var dragonBreathQuantity = 5.0
val onePint=0.125
val showPintCountThreshhold = 12
fun main() {
displayRemaningDragonsBreath(0)
placeOrder(“shandy,DRAGON’S BREATH; IT’S GOT WHAT ADVENTURES CRAVE,5.91”)
displayRemaningDragonsBreath(13)
}
fun placeOrder(menuData:String){
try {
val indexOfApostrophe = TAVERN_NAME.indexOf(’’’)
val tavernMaster = TAVERN_NAME.substring(0 until indexOfApostrophe)
println(“Madrigal speaks with tavernMaster about their order") /*val data = menuData.split(",") val type = data[0] val name = data[1] val price = data[2]*/ val (type,name,price) = menuData.split(',') val message = "Madrigal buys a {name.split(’;’)[0].toLowerCase().capitalize()} ($type) for $price”
val phrase = “Ah, delicious $name”
println(message)
performPurchase(price = price.toDouble())
println(toDragonSpeak(phrase))
}catch (e:Exception){
println(e)
println(“Oh No!. Details not fully entered.”)
}
}

fun toDragonSpeak(phrase:String)=phrase.replace(Regex("[aAeEiIoOuU]")){
when(it.value){
“a”->“4”
“e”->“3”
“i”->“1”
“o”->“0”
“u”->"||"
“A”->“4”
“E”->“3”
“I”->“1”
“O”->“0”
“U”->"||"
else->it.value
}
}
fun performPurchase(price: Double){
displayBalance()
val totalPurse = playerGold+(playerSilver/100.0)
println(“Total purse: $totalPurse”)
println(“Purchasing item for price") val remainingBalance=totalPurse-price println("Remaning Balance: {”%.2f".format(remainingBalance)}")
val remaningGold = remainingBalance.toInt()
val remainingSilver = (remainingBalance%1*100).roundToInt()
playerGold=remaningGold
playerSilver=remainingSilver
displayBalance()
}
private fun displayBalance(){
println(“Player’s purse balance: Gold: $playerGold, Silver $playerSilver”)
}
private fun displayRemaningDragonsBreath(purchasedquantity:Int){
dragonBreathQuantity -= (purchasedquantity * onePint)
println(“Remaining Breath (Gallons): dragonBreathQuantity") if(purchasedquantity>=showPintCountThreshhold){ println("Remaining Pints: {(dragonBreathQuantity/onePint).roundToInt()}”)
}
}

Here is my solution:

Tavern.kt 
import kotlin.math.roundToInt

const val TAVERN_NAME = "Taernyl's Folly"

var playerGold = 10
var playerSilver = 10

var dragonBreathCaskGallons = 5.0
const val PINT_IN_GALLON = 0.125
var dragonBreathCaskPints = dragonBreathCaskGallons / PINT_IN_GALLON
var dragonBreathOrders = 0

fun main() {
    for (i in 1..15) {
        println("--- Order number: $i ---")
        placeOrder("shandy,Dragon's Breath,5.91")
    }
//    placeOrder("elixir,Shirley's Temple,4.12")
}

fun performPurchase(price: Double) {
    displayBalance()
    val totalPurse = playerGold + (playerSilver / 100.0)
    println("Total purse: $totalPurse")
    println("Purchasing item for $price")

    val remainingBalance = totalPurse - price
    println("Remaining balance: ${"%.2f".format(remainingBalance)}")

    val remainingGold = remainingBalance.toInt()
    val remainingSilver = (remainingBalance % 1 * 100).roundToInt()
    playerGold = remainingGold
    playerSilver = remainingSilver
    displayBalance()
}

fun displayBalance() {
    println("Player's purse balance: Gold: $playerGold , Silver: $playerSilver")
}

private fun toDragonSpeak(phrase: String) =
    phrase.replace(Regex("[aeiou]")) {
        when (it.value) {
            "a" -> "4"
            "e" -> "3"
            "i" -> "1"
            "o" -> "0"
            "u" -> "|_|"
            else -> it.value
        }
    }

private fun placeOrder(menuData: String) {
    val indexOfApostrophe = TAVERN_NAME.indexOf('\'')
    val tavernMaster = TAVERN_NAME.substring(0 until indexOfApostrophe)
    println("Madrigal speaks with $tavernMaster about their order.")

    val (type, name, price) = menuData.split(',')
    val message = "Madrigal buys a $name ($type) for $price"
    println(message)

    performPurchase(price.toDouble())

    val phrase = if (name == "Dragon's Breath") {
        "Madrigal exclaims: ${toDragonSpeak("Ah, delicious $name!")}"
    } else {
        "Madrigal says: Thanks for the $name"
    }
    println(phrase)

    if (name == "Dragon's Breath") {
        dragonBreathOrders++
        dragonBreathCaskPints--
        if (dragonBreathOrders >= 12) displayDragonBreathPintsLeft()
    }
}

private fun displayDragonBreathPintsLeft() {
    println("Dragon Breath pints left: ${dragonBreathCaskPints.toInt()}")
}
