Scenario : You want to calculate how many pounds of fertilizer you will need to

Question

Scenario:

You want to calculate how many pounds of fertilizer you will need to buy to supply 1.0 pounds of Nitrogen per 1000 square feet to your lawn. The first number of the three number entries on the fertilizer bag represents what percentage of the fertilizer is Nitrogen. (For example a 20-10-10 fertilizer has 20% Nitrogen). All in C#

Inputs:

1) The length of your lawn in feet

2) The width of your lawn in feet

3) The percentage of Nitrogen in the fertilizer you intend to use

Processing:

1. Calculate the number of square feet in your lawn

2. Divide the number of square feed by 1000 to get the number of pounds of Nitrogen you need

3. Convert the percentage number from the input to a decimal number by dividing by 100.

4. Calculate the number of pounds of fertilizer needed by dividing the number of pounds of Nitrogen you need by the percentage of Nitrogen in the fertilizer.

Output:

Display a nicely worded message that indicates how many pounds of fertilizer you will need with 2 decimal places.

Explanation / Answer

using System;

public class Test
{
   public static void Main()
   {
       //input length and width of lawn
       Console.WriteLine("Enter the length of your lawn in feet");
       double length = Convert.ToDouble(Console.ReadLine());
       Console.WriteLine("Enter the width of your lawn in feet");
       double width = Convert.ToDouble(Console.ReadLine());
      
       //input % of nitrogen in the fertilizer
       Console.WriteLine("Enter the percentage of Nitrogen in the fertilizer you intend to use");
       double nitrogenBag = Convert.ToDouble(Console.ReadLine());
      
        double area = length * width; //calculate area of lawn
        double nitrogenNeed = area /1000; // nitrogen needed per 1000 square
        double nitrogenBagPer = nitrogenBag/100; //calculate nitrogen percentage
       
        double fertilizer = nitrogenNeed/nitrogenBagPer;// fertilizer needed in pounds
       
        Console.WriteLine("The pounds of fertilizer you will need to buy to supply 1.0 pounds of Nitrogen per 1000 square feet to your lawn : {0:F2}",fertilizer);
       
       
   }
}
