Quizplus · Accepted Answer

An increase in the incomes of buyers would lead to an increase in demand for The Movie Network subscriptions as consumers have a higher purchasing power and are more likely to subscribe to the service. This would shift the demand curve to the right. A fall in the price of The Movie Network subscriptions (A) or an increase in the supply of The Movie Network subscriptions (C) would also increase demand, but these factors are not mentioned in the question. An increase in the price of The Movie Network subscriptions (B) would actually shift the demand curve to the left, as consumers would be less willing to pay for higher prices.
