Create a class that will bundle together several static methods for tax computations. This class should not have a constructor. Its attributes are

• basicRate—the basic tax rate as a static double variable that starts at 4 percent • luxuryRate—the luxury tax rate as a static double variable that starts at 10 percent Its methods are • computeCostBasic(price)—a static method that returns the given price plus the basic tax, rounded to the nearest penny. • computeCostLuxury(price)—a static method that returns the given price plus the luxury tax, rounded to the nearest penny. • changeBasicRateTo(newRate)—a static method that changes the basic tax rate. • changeLuxuryRateTo(newRate)—a static method that changes the luxury tax rate. • roundToNearestPenny(price)—a private static method that returns the given price rounded to the nearest penny. For example, if the price is 12.567, the method will return 12.57.
