Prediction of a Car's Miles per Gallon (MPG)

This is a Reproducible Pitch Presentation about my Shiny application.

It allows you to predict your car's expected Miles per Gallon (MPG) based on your car's specifications.

These specifications include:

1. The Type of Transmission (Automatic vs. Manual).
2. The Number of Cylinders.
3. The Car's Weight.
4. The Car's Gross Horsepower.

The purpose of this application is to allow users to predict their car's Miles per Gallon (MPG) with ease by entering their car's specifications.

These specifications include the type of transmission, the number of cylinders, the car's weight and gross horsepower.

This will allow users to have a better idea of the mileage they have achieved based on each gallon of fuel exhausted.
