## 2.21 LAB: Expression for Calories Burned During Workout

The following equation estimates the average calories burned for a person when exercising, which is based on a scientific journal article (source):

\[ \text{Calories} = \left( (\text{Age} \times 0.2757) + (\text{Weight} \times 0.03295) + (\text{Heart Rate} \times 1.0781) - 75.4991 \right) \times \frac{\text{Time}}{8.368} \]

Write a program using inputs age (years), weight (pounds), heart rate (beats per minute), and time (minutes), respectively. Output the average calories burned for a person.

Output each floating-point value with two digits after the decimal point, which can be achieved as follows:
```java
System.out.printf("%.2f", yourValue);
```

### Example

If the input is:

```
49 155 148 60
```

The output is:

```
Calories: 736.21 calories
```

This program will help in calculating the energy expenditure for given parameters, aiding individuals in understanding their fitness metrics more accurately.

### LAB Activity: Expression for Calories Burned During Workout

**Example Output:**
If the input is:
```
49 155 148 60
```

The output is:
```
Calories: 736.21 calories
```

**Image Explanation:**
1. The image contains a snippet from an educational website which appears to be part of a programming exercise related to calculating calories burned during a workout. 

2. The example provided shows four input numbers (`49 155 148 60`) and the resultant output after some calculations (`Calories: 736.21 calories`).

**Java Programming Context:**
The shown code template is the starting point for writing a program to solve the specified problem.

```java
import java.util.Scanner;

public class LabProgram {
    public static void main(String[] args) {
        // Code implementation goes here
    }
}
```

In the provided `LabProgram.java`:

1. The `import java.util.Scanner;` statement at the beginning of the code allows the program to use the `Scanner` class for reading input values.
2. The class `LabProgram` contains a `main` method, which is typically the entry point for a Java application.
3. The `main` method has a place for students to write their code to perform the required calculations based on the given input example.

The exercise likely involves reading the input values, performing some arithmetic operations to calculate the calories burned, and then outputting the result in a formatted string.
