Permintaan Dan Penawaran

The factors that affect demand are price of goods, level of income, and consumer preferences. These factors determine the quantity of a good or service that consumers are willing and able to purchase at a given price. In this case, options 1, 2, and 3 include all three factors, making them the correct answer. Option 1 includes the price of goods, level of income, and consumer preferences. Option 2 includes the price of goods, consumer preferences, and cost of production. Option 3 includes the level of income, consumer preferences, and cost of production. Therefore, the correct answer is 1, 2, and 3.

Based on the given table, the equilibrium price in the market is Rp 15,000. This can be determined by looking at the point where the quantity demanded and quantity supplied intersect. At a price of Rp 15,000, the quantity demanded is 350 and the quantity supplied is also 350. This indicates that at this price, the market is in balance and there is neither excess demand nor excess supply. Therefore, Rp 15,000 is the correct answer for the equilibrium price.

The correct answer is "cateries paribus". This term refers to the assumption that all other factors remain constant or unchanged when analyzing the relationship between two variables in economics. It helps economists isolate the impact of a single factor on an economic phenomenon.

The correct answer states that when the price increases, the demand decreases. This is known as the law of demand, which states that there is an inverse relationship between price and quantity demanded. As the price of a good or service increases, consumers are less willing and able to purchase it, resulting in a decrease in demand. This is a fundamental concept in economics and helps to explain the behavior of consumers in response to changes in price.

The correct answer is "Harga bertambah penawaran bertambah". This is because when the price increases, suppliers are willing to produce and sell more goods, leading to an increase in the quantity supplied. This relationship is represented by an upward-sloping supply curve.

The correct answer is "Absolut, potensial dan efektif". This answer is correct because it lists the types of demand that are considered based on their purchasing power. Absolute demand refers to the total demand for a product or service in the market. Potential demand refers to the maximum demand that could be achieved if all potential buyers were to purchase the product or service. Effective demand refers to the actual demand that is backed by purchasing power and willingness to buy. Therefore, the answer accurately identifies the types of demand based on their purchasing power.

The demand for a good is said to be elastic when a small change in price leads to a significant change in quantity demanded. In this case, the demand for a car (mobil) is likely to be elastic because cars are considered luxury goods and consumers are more sensitive to changes in their prices. If the price of cars increases slightly, consumers may choose to delay their purchase or opt for alternative modes of transportation. Conversely, if the price decreases, consumers may be more inclined to buy cars.

The factors that affect the quantity of supply are 1, 3, and 5. This means that the factors of income, availability of production resources, and the emergence of new producers have an impact on the quantity of supply.

The coefficient of price elasticity of demand measures the responsiveness of quantity demanded to a change in price. In this case, the price of the product is Rp 1,000 and the quantity demanded is 20 units. If the price were to increase by 1 unit, the quantity demanded would decrease by 20 units. Therefore, the coefficient of price elasticity of demand is 1, indicating that the demand is unitary elastic.
