·Company A has 50 shares outstanding valued at $2 each.
·Company B has 10 shares outstanding valued at $10 each.
·The price-weighted index is 6, and the value-weighted index is 100.
If the price of Company A's stock increases to $4 per share, and Company B's stock splits two-for-one and is priced at $5, the value of the price-weighted index and the value-weighted index are:
