So I've been trying to wrap my brain around this but it eludes me. The word problem would look something like this:
What is the minimum amount of seeds I need to buy to plant 850 seeds when only 60% of these planted seeds will produce a seed of their own. I can continue planting over and over until I reach my last seed.
I am looking for a formula I can use and plug into Excel - but a mathematical equation would be just great!
