(Financial: compare costs) Suppose you shop for rice in two different packages. You would like to write a program to compare the cost. The program prompts the user to enter the weight and price of the each package and displays the one with the better price. Here is a sample run: Enter weight and price for package $1: 50 \quad 24.59$ Enter weight and price for package 2: 2511.99 Package 1 has a better price.

Key Concepts

Unit Price Calculation

This concept involves determining the cost per unit weight by dividing the total price by the package's weight. It is a fundamental technique in comparing the cost-effectiveness of different products, allowing for a fair comparison regardless of the package sizes.

Arithmetic Operations

Basic arithmetic operations, particularly division, are used to compute the unit price. Understanding how to perform these calculations correctly is essential for evaluating ratios and comparing different quantities.

Conditional Logic

Conditional statements are used to compare the computed unit prices and decide which package offers a better deal. This logic is central to making decisions based on numerical comparisons in many programming tasks.

User Input/Output

Gathering input from the user and displaying the results is crucial for interactive programs. It involves prompting the user for necessary data, processing that data, and providing clear feedback based on the computation.
