    Default Homework help!

    Hi guys! total beginner here at java and need some help or guidance, I have the basic skeleton of code for this problem but am at a lost to actually knowing what to put down for the "equation". Maybe you guys can help me out?

    Sammy's Seashore Suppliers rents beach equipment such as kayaks, canoes, beach chairs, and umbrellas to tourists. Write a program that prompts the user for the number of minutes he rented a piece of equipment. Compute the rental cost as $40 per hour plus $1 per additional minute. Then display the hours, minutes, and total price. Save the file as SammysRentalPrice.java

    This is what I came up with so far:

    import java.util.Scanner;
    public class SammysRentalPrice {
     
    	public static void main(String[] args) {
     
    		int minutes;
    		int hours;
    		int additionalMinutes;
    		double price;
     
    			System.out.print("How many minutes ");
    			minutes = input.nextInt;
     
    			hours= minutes
     
    	}
     
    }

    What exactly are you trying to figure out? How would you figure it out with a piece of paper and a pencil, without a computer?

    Sorry edited my post. And I'm trying to figure out how to calculate the price of the rental, by prompting the user to enter how many minutes they would be renting for, at $40 an hour, plus $1 per additional minutes. While displaying the total hours, minutes, and total price. Such as "For the rental of x hours + additional x minutes, the price is X amount.

    Cool, knowing what you're trying to figure out is the first step.

    Now that you know what you're trying to figure out, which part of that are you stuck on?

    How to do the arithmetic part of it, it's just right after the system.out.print.

    You have to break your problem down into smaller steps. Separate the user input from the arithmetic part.

    Since you're stuck on the arithmetic part, then simply hardcode the variables you know you're going to need to some predefined values. Then write the code that takes those variables and does the correct arithmetic with them. Which part of the arithmetic are you stuck on? How would you figure this out in your head, without a computer?

    When you get that working perfectly, then you can worry about getting the variable values from the user.

    Like do you mean for every minute it's 1 dollar ?
    and for every hour it's 60 - 20 dollars?

    Yes there are 'better' ways to do it but it's good to start simple.
    modulos can wait.
