//sample solution


var cashRegisterWithChange = {
    total: 0,
    change: 0,  
    coinNames: ["five dollar bills", "one dollar bills", "quarters", "dimes", "pennies"],
    currency: [5.00, 1.00, 0.25, 0.10, 0.01],
setTotal: function (amount) {
this.total = amount;
},
getPaid: function (amountPaid) {
if (this.total > amountPaid) {
console.log ("Not enough!");
} else {
            this.change = amountPaid - this.total;
console.log ("Give them:");
            this.makeChange(this.coinNames, this.currency, 0);
}
},
    howManyCoins: function (coinName, coinAmount, coinsSoFar) {
        if (this.change < coinAmount) {
            console.log(coinsSoFar + " " + coinName);
        } else {
            this.change -= coinAmount;
            this.change = this.change.toFixed(2);
            this.howManyCoins(coinName, coinAmount, coinsSoFar + 1);
        }
    },
    makeChange: function(coinNames, currency, index) {
if (index >= currency.length) {
return;
} else {
this.howManyCoins(coinNames[index], currency[index], 0);
this.makeChange(coinNames, currency, index + 1);
}
}
};  
//and leave these calls to check if you get the correct output
cashRegisterWithChange.setTotal(100);
cashRegisterWithChange.getPaid(50);
cashRegisterWithChange.getPaid(109.94);
