Answer: 300 shares at $31.50
Explanation:
The NASDAQ system simply uses an index, or sometimes stick collection that are being utilized to make a snapshot of the market performance.
A market maker enters a quote of $31.50 Bid; $32.00 Ask; with a size of "3 x 5" into the NASDAQ System. If a market order to sell is entered into the system for 500 shares, and this dealer's quote is matched, the market maker will be obligated to buy 300 shares at $31.50.
