i am in the seventh grade an for social studies we are doing a senate simulation... so, i have to write a bill my bill is about changing the we change all Navy, Army and Air force diesel engines to biodiesel to save money...... one of the facts that is important to include is how much total this project would cost, this project is mainly for the Navy Air force and Army.... so even if you know a number such as "over 123 million" that would be VERY helpful. And please DO NOT write that there is not a number and that no one knows......


Please help me if you can!!! Thank you for taking the time to read this!!!
