If you purchased 1 share of Apple back in 2004, it would have turned into 2 shares in 2005. Those two shares would have turned into 7 shares each in 2014, so the original 1 share would now be 14 shares (1 x 2 x 7).

If your original investment in that first share was $2 (1 share x $2 = $2), that $2 would now be worth $2,800 (14 shares x $200/share = $2,800).

So, simply multiply the original number of shares he would have purchased by 14, then multiply that by $200, and you'll know what your inheritance would have been if you would have been smart enough to push your dad to invest back then.

Then never think about it again, because it was an opportunity missed.

However, I'm pretty sure that Apple wasn't trading at $2 back in 2004. That is probably the split adjusted price.
