33. Write a method The above formula calculates a person’s BMI given their height in centimeters and weight in kilograms. Write a method to calculate a person’s BMI given their height and weight, but the weight is given in grams. (1 kilogram = 1000 grams). public double bmi(double wt, double ht){

34. Write a method You need to write a program to help out your weekend business doing lawn care. You really need to buy $15 bags of grass seed, but if any money is left over, you also need some $2 bags of mulch. Write a method that takes as input how much money you have and prints how many bags of grass seed and mulch I can buy. For example, if I have 52 dollars, I can buy 3 bags of seed (that’s $45) and 3 bags of mulch ($6 more). public void purchaseOrder(int dollars) The line System.out.println(x) prints the value of the variable x.
