Answer:
42
Explanation:
The quantity wholesalers wish to purchase reflects demand at a given price. At $ 18 a bushel, wholesalers want to buy 42 bushel of wheat. This result can be seen from the graph that tells us that at the price of US $ 18, demand will be 42, that is, the price (US $ 18) intersects the demand curve in the quantity that wholesalers want to buy (42 bushels).
