Round 2

Team

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){

Write a methodYou 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)

Write a method• The method takes as parameters the rate (amount per

hour) the employee makes and the number of hours worked. Employees make the pay rate for the first 40 hours they work, and overtime pay for any hours worked after that. Overtime pay is 1.5 times regular pay rate.

• For example, getPayAmount(10, 30) should return 300, and getPayAmount(10, 45) should return 475.

 • public double getPayAmount(double rate, double hours){
