Radioactive carbon-14 dating has determined that a fossil is 5.7 x 10 to the third power years old. What is the total amount of the original Carbon-14 still present in the fossil?

The half life of carbon 14 is 5700 years. So If a fossil is 5700 years old then half of the carbon-14 is left.

I don't have the answer to your question, but I do know, however, that I have an amazing freaking voice. And if you'd like, I will write a book about your life and then narrate it, with my awesome freaking voice. But I cannot answer your question. I am NOT sorry.
