    // Ask the user for how many of each they want, then print the subtotal.  Then calculate the tax (Maine food tax is 7%)
    // Print out the tax and then the total of the order.
    // So if they ordered 3 burgers, 3 drinks and 2 fries it would say
    // Your subtotal is $16.80.  
    // The tax is $1.176
    // Your total is $17.976

Students finished early - must do below (note on if statements, loops)
     //Ask the user for a number of miles for a taxi ride and then ask for
    // cost per mile and pickup cost. 
    //Then spit out total charge (which is #of miles *cost per mile + pickup cost

    }

    //This will ask the user for the speed he was going and then spit out
    //the cost of a ticket (from 0-65 - $0, 66-74 - $85, 75-100 - $200 101+ - $1000

    //This will find out the number of people who dressed up for spirit week
    //Ask the user 5 times (for each day) how many people dressed up [like how many people dressed up on day1? etc]
    //Then spit out the total
    //you must use a for loop

    {
    }
    
    //This will ask the user how many games they played, then it will find the winning percent 
    //So the user might say 3, and the program will ask them 3 times if they won
    //So they might say y,n,n and then it will spit out you won 33.3% of the time
    public void findWinningPrct()
    {
    }
    
    //create a method that will keep asking for a grade until the user hits -1.  They will then
    //find the average of those grades
    // you will need to use loops
    public void findAverage()
    {
    }
