How many 10MB jpeg files will fit on a 4.7GB DVD disc?

I have a Nikon D5100. I want to have the settings setup as Fine and Large which means each file will be about 10MB's big. How many of these 10MB jpeg's can get burned to a DVD?

I expect to take like 800 or so at a wedding this saturday and wondered if they might fit.on one disc.

Thanks!
