Question

Herbert’s Home Repair estimates each job cost as the cost of materials plus $35 per hour while on the job, plus $12 per hour for travel time to the job site.

The main() method prompts the user for the name of a job (for example, Smith bathroom remodel), the cost of materials, the number of hours of work required, and the number of hours travel time.

Pass the numeric data to a method that computes an estimate for the job and returns the computed value to the main() method which displays the job name and estimated price.

import java.util.Scanner;

class JobPricing {

public static void main(String[] args) {

String description;

double materials;

double hoursOnJob;

double hoursTraveling;

double price;

Scanner input = new Scanner(System.in);

System.out.print("Enter job description >> ");

description = input.nextLine();

System.out.print("Enter cost of materials >> ");

materials = input.nextDouble();

System.out.print("Enter hours on the job work >> ");

hoursOnJob = input.nextDouble();

System.out.print("Enter hours traveling >> ");

hoursTraveling = input.nextDouble();

price = computePrice(materials, hoursOnJob, hoursTraveling);

System.out.println("The price for " + description +

" is $" + price);

}

public static double computePrice(double materials, double hours, double travel) {
