Consider a hypothetical price-weighted index created using the three stocks below:

Stock	Price before split	Price after split	Outstanding Shares (mil) before split	Outstanding Shares (mil) after split
X	$80	$80	400	400
Y	100	100	1000	1000
Z	30	3	500	5000

Yesterday before market close, Stock Z has completed a 10-for-1 split. Prices before and after the split are listed above. Before the split, you were holding 179 shares of each of the stocks.

After Stock Zs 10-for-1 split, you realize that you need to adjust the portfolio so that it can stay price-weighted. To do so, how many shares of X would you need to buy?

Round your answer to the nearest whole number.
