Multiple Parameters Method: Total Price Calculator

Easy

Problem Description

Multiple Parameters method: Total Price Calculator

Learning Objective: Define methods with multiple parameters

In this problem, you will create a program that defines a calculateTotal method accepting three parameters (unit price, quantity, and tax rate), computes the total price (unit price × quantity × (1 + tax rate)), and displays the result to standard output.

Create a program calculating total price from three information pieces: unit price, quantity, tax rate. Pass multiple arguments to the calculateTotal method.

Input

Line 1: Unit price (integer)
Line 2: Quantity (integer)
Line 3: Tax rate (decimal, e.g., 0.1 is 10%)

Output

Unit price: [price] yen
Quantity: [quantity] items
Tax rate: [rate]
Total: [total] yen
