Question

Write an if statement that multiplies payRate by 1.5 if hours is greater than 40 .

Short answer

Answer: The if statement in the provided solution checks whether the 'hours' variable is greater than 40. If the condition is met (i.e., 'hours' > 40), it multiplies the 'payRate' by 1.5 to calculate an increased pay rate for the employee. If the condition is not met, the code inside the if block does not execute, and the 'payRate' remains unchanged.

Step-by-step solution

1. Initialize the variables

First, initialize the variables 'hours' and 'payRate'. For this example, let's assume the hours worked by a student is 45 and the payRate is 10. ```python hours = 45 payRate = 10 ```

2. Create the if statement

Create an if statement that checks whether 'hours' is greater than 40. If true, then multiply payRate by 1.5. ```python if hours > 40: payRate = payRate * 1.5 ```

3. Explanation of the if statement

The if statement checks if the condition 'hours > 40' is True. If it is, then it proceeds to execute the code within the if block, which is 'payRate = payRate * 1.5'. This multiplies the original payRate by 1.5 and saves the result back into the 'payRate' variable. If the condition is False, the code within the if block does not execute and the payRate remains unchanged.

4. Display the result

Lastly, we can print the final payRate to see the result. Note that if 'hours' was not greater than 40, this would print the original payRate. ```python print("Pay Rate:", payRate) ```

Key concepts

Python Programming

Python is a widely-used programming language known for its simplicity and readability. It’s often the first language developers learn due to its straightforward syntax. In Python, you can easily perform tasks that require less code when compared to other languages. This makes it an ideal tool for beginners and for experienced coders who want to quickly develop solutions to problems.

One of the powerful features of Python is its vast array of libraries and frameworks, which enable you to handle complicated tasks with ease. From web development to data analysis and beyond, Python has robust tools for almost any programming need.

In our exercise, we use Python to perform arithmetic operations and create conditional statements. Creating an if statement that multiplies payRate reflects Python's straightforward syntax, where conditions and arithmetic manipulation can be performed with just a few lines of code.

Control Structures

Control structures in programming are used to direct the flow of the program. They allow developers to decide what sections of code to execute based on certain conditions. The "if statement" is a control structure in Python that helps in making decisions within the code.

The basic syntax of an if statement in Python helps to check a condition, and if that condition is true, it executes the block of code indented below it. This simplicity and clarity make it easy to create pathways in your program that adapt to different input or circumstances. In the provided exercise, the if statement checks whether the number of worked hours is greater than 40. If it is, the code multiplies the payRate by 1.5, showcasing how effectively control structures can manage conditional logic.

Problem Solving with Code

Problem-solving with code involves breaking down a task or challenge into its components and then writing code to solve each part. It often requires developers to think logically and understand the problem's requirements fully before jumping into coding.

In our exercise, the main problem is determining when to adjust a worker’s payRate based on their hours worked. Breaking it down involves identifying the boundaries (hours greater than 40) and deciding the action to take if the condition is met (multiplying payRate by 1.5). This logical breakdown helps in writing clear and concise code.

Effective problem-solving in programming not only involves writing correct code but also writing it in a way that others can understand. That's the essence of Python’s syntax - clarity and readability. Thus, by framing the problem clearly and logically using control structures like the if statement, we can create efficient and maintainable code that solves the problem specifically and effectively.
