which of the following would cause an increase in the demand for beef?\na. an increase in the number of firms in the market.\nb. an increase in the price of fish, a substitute for beef.\nc. a decrease in the price of beef.\nd. a decrease in consumer incomes (beef is a normal good).

Answer

Brief Explanations:

When the price of a substitute (fish) increases, consumers will shift their demand towards the alternative good (beef), increasing beef's demand. An increase in the number of firms affects supply, not demand. A decrease in beef's price causes a movement along the demand - curve, not a shift in demand. A decrease in consumer incomes for a normal good reduces demand.

Answer:

B. An increase in the price of fish, a substitute for beef.
