Trades cost a minimum of $8, so 10 x $8 is $80.
However, you also have to sell whatever you buy at a profit to ensure you don't make losses there too.
If you're not familiar with shares, I'd say this isn't worth it. And even if you are, it's pretty line ball imo, esp as the average value of those points is $100 anyway. You're paying close to that just in trade fees, assuming you don't make any losses at all on the trades. In your case, where as you say you have no experience with trading, I'd say this isn't a good way for you to gain experience...
