If an increase in production costs leads to a decrease in supply, then a decrease in consumer demand leads to what change in the market? A:Increase in price; B:Increase in quantity supplied; C:Decrease in price; D:Decrease in quantity demanded

When production costs go up, it becomes more expensive for producers to make goods, which means they supply less of those goods. If at the same time, consumer demand decreases, it means fewer people want to buy those goods. This combination usually leads to a decrease in price because sellers will lower prices to attract more buyers and sell their excess products. For example, if a toy company produces fewer toys due to high costs and fewer kids want to buy them, the company may lower prices to encourage sales. Therefore, the correct answer is C: Decrease in price.
