I've only used dry yeast a few times, and just used the whole pack. You
want the most yeast you can to get a good strong fermentation started.
The only times I've had open packages is when I've made soda. I just
put the opened pack in a zip top bag and stuck it back in the fridge for
another batch (actually a few) of soda. If you make bread, you could
add it to your bread yeast. I've done this a few times. Otherwise, dry
yeast is cheap, so just toss it out.
