Calculating Water Bill

Introduction

In this article, we will explore how to calculate a water bill with an increasing rate per unit based on consumption. Many utility companies charge higher rates as the water consumption increases, which requires a dynamic calculation. By following the step-by-step solution provided in this article, you will be able to calculate the water bill accurately, taking into account the varying rates per unit.

Understanding the Problem

The problem involves calculating the water bill based on the water consumption and the increasing rate per unit. We need to consider the consumption levels and apply the appropriate rate to calculate the total bill.

Approach

To solve this problem, we will use conditional statements to determine the applicable rate per unit based on the consumption level. We will then multiply the consumption by the corresponding rate and calculate the total bill.

Step-by-Step Solution:

Step 1: Accepting User Input 

Start by accepting the water consumption from the user. You can use the Scanner class in Java to achieve this.

Step 2: Determining the Applicable Rate per Unit

Using conditional statements, determine the rate per unit based on the consumption level. You will need to define the rate brackets and their corresponding rates.

Step 3: Calculating the Water Bill

Multiply the consumption by the applicable rate per unit to calculate the cost for each bracket. Sum up the costs for all the brackets to obtain the total bill.

Step 4: Displaying the Result

Finally, print the total bill to the user.

Code Implementation

Now, let's put the steps into code and solve the problem:
