Add the following constants in the class definition, before the main method:
    private final static float START_COST = 1.5f;
    private final static float HIGH_TARIFF = 0.5f;
    private final static float LOW_TARIFF = 0.25f;
    private final static int FIXED_MINS = 2;
    private final static int HIGH_TARIFF_MINS = 10;
Then add this to the main method you already had:
        float price = START_COST;
        if (x > FIXED_MINS) {
            if (x <= HIGH_TARIFF_MINS) {
                price += HIGH_TARIFF*(x-FIXED_MINS);
            }
            else {
                price += HIGH_TARIFF*(HIGH_TARIFF_MINS-FIXED_MINS) 
                    + LOW_TARIFF*(x-HIGH_TARIFF_MINS);
            }
        }   
        System.out.printf("A %d minute call costs %.2f", x, price);      
        
             
        
        
        
Answer: key escrow
