How much should I charge for animation?

[javamcp]

I'm creating 101 5-10 second animations for a company who plans to publish a book with QR codes linked to my animations.
The animations are of similar quality to these animation that I've created:

I'm just having trouble trying to figure out how much i should charge.
Is $500 dollars for each set of 50 animations too little?

You should generally charge a living wage for the time it takes to produce the animation.

Each animation takes 15-20 minutes to make...
Any idea on what a reasonable price would be?

Take the time to produce, including content creation (not just animating), and multiply that by the hourly wage you require to make a living. Reasonable is only somewhere between what it takes to not starve doing a job and what the market/customer will bear.

Thank you.
Your advice was very helpful.
