Quizplus · Accepted Answer

A decrease in the number of popcorn producers would lead to a decrease in the supply of popcorn, as there would be fewer producers in the market producing popcorn. An increase in the price of popcorn would not decrease supply, but rather increase it, as more producers would enter the market to take advantage of the higher prices. Similarly, a decrease in the price of popcorn would not decrease supply, but increase it. A technological advance in the production of popcorn would increase the efficiency of production and thus increase the supply of popcorn.
