                /* You're staying in NYC for a month. There's so much to do and see but you're presented with 1 tough decision: buy a monthly MetroCard for $127 or a pay-per-ride MetroCard that costs $2.75 per swipe?

1. Write a function that takes in a number of rides and returns the savings you'd receive from buying a monthly card. If the savings are negative, that means you'd save more from buying a pay-per-ride card!

2. Write another function that takes in the savings returned from the previous function. This function should return a message that either suggests to buy a monthly MetroCard or a pay-per-ride. This message should also include how much you'd be saving if you buy this card.

Use printToScreen() to print the messages returned from function 2 for 30 rides, 45 rides, 60 rides, and a user-inputted custom number of rides!

Note: use toFixed(2) to round to the nearest 2 decimal points

// Enter your code below this line

const metrocard1 = (rides) => {
  let answer = rides*2.5;
  return answer-127;

//let savings = printToScreen(metrocard1(5))


const metrocard2 = (savings) => {
  let rideNumber = savings;
  let answer = savings*2.75;
  answer = answer-127;
  var answer1 = answer.toFixed(2)
  if(answer1 == 0 || answer1 > 0){
    printToScreen("With " + rideNumber + " rides")
    printToScreen("You should purchase a monthly MetroCard! Your savings will be " + answer1)
  if(answer1 < 0){
    let answer2 = Math.abs(answer1)
    var answer3 = answer2.toFixed(2)
    printToScreen("With " + rideNumber + " rides")
    printToScreen("You should purchase a pay-per-ride MetroCard! Your savings will be " + answer3)
let userRides = prompt("How many rides?")



function printToScreen(text) {
  let r = Math.floor(Math.floor(Math.random() * 255 + 1));
  let g = Math.floor(Math.floor(Math.random() * 255 + 1));
  let b = Math.floor(Math.floor(Math.random() * 255 + 1));
