4.16 LAB: Driving cost-methods Write a method drivingCost() with input parameters milesPerGallon, dollarsPerGallon, and milesDriven that returns the dollar cost to drive those miles. All items are of type double. The method called with arguments (20.0, 3.1599, 50.0) returns 7.89975. Define that method in a program whose inputs are the car's miles per gallon and the price of gas in dollars per gallon (both doubles). Output the gas cost for 10 miles, 50 miles, and 400 miles, by calling your drivingCost() method three times. Output each floating-point value with two digits after the decimal point, which can be achieved as follows: System.out.printf("%.2f", yourValue); The output ends with a newline. Ex: If the input is: 20.0 3.1599 the output is: 1.58 7.90 63.20 Your program must define and call a method: public static double drivingCost (double milesPerGallon, double dollars PerGallon, double milesDriven) 357658.1724120.qxaxy7 LAB ACTIVITY 4.16.1: LAB: Driving cost-methods 4/10 LabProgram.java Load default template... 1 import java.util.Scanner; 3 public class LabProgram { 1234 600 0 /* Define your method here */ 7 public static void main(String[] args) { 8 /* Type your code here. */ 9 } 5 10 } 11

Activity 2 7.) Write a program that will calculate and print out bills for the city water company. The water rates vary depending on whether the water is for home use, commercial use or industrial use. A code of H means home use, a code of c means commercial use and a code of I means industrial use. The water rates are computed as follows: code H: P250.00 plus P0.002 per gallon used code c: P5,000.00 for the first 4 million gallons and P0.002 for each additional gallon. code I: P8,000 if usage does not exceed 4 million gallons, P14,000 if usage is more than 4 million gallons but not more than 10 million gallons and P18000 if usage exceeds 10 million gallons. Your program should prompt the user for the code and the gallons of water used. Your program should echo your input data and should print the amount due from the user. Your program should use a switch statement for the code (char data type). Use the float data type for the gallons. Sample Output in the images:

5.23 In Python: Write a program with total change amount as an integer input that outputs the change using the fewest coins, one coin type per line. The coin types are dollars, quarters, dimes, nickels, and pennies. Use singular and plural coin names as appropriate, like 1 penny vs. 2 pennies. Ex: If the input is: 0 or less, the output is: no change Ex: If the input is: 45 the output is: 1 quarter 2 dimes Your program must define and call the following function. The function exact_change() should return num_dollars, num_quarters, num_dimes, num_nickels, and num_pennies.def exact_change(user_total)
Program 1: Write a program that asks the user to input a sentence and then outputs the sentence back with the case of every character reversed. So for example: “CaTs RuLe!” would be given back as “cAtS rUlE!” . Spaces and punctuation should be left in place. You can use the Character class static functions to test the case of each letter. You do not need to place any code in static methods (besides the main method), you do not need to worry about try/catch blocks, and you do not need to make the program run more than once. in java
