//First Problem Solution

  }

//Second Problem Solution

//Third Solution
//Ran out of time before I could incorporate solution if amount is a percentage. Would need to write helper function that converts that to seconds to be able to fully complete problem

    const hours = Math.floor(seconds / 3600)
    const minutes = (seconds % 3600) / 60
    const remainingSeconds = seconds - (hours * 3600) - (minutes * 60)
    return "" + hours + ":" + minutes + ":" + remainingSeconds
