Answer:
demand curve for product J would shift rightwards or outwards
If X is a normal good, an increase in income would shift the demand curve rightwards or outwards
Step-by-step explanation:
Substitute goods are goods that can be used in place of another good.
If the price of product L increases, the quantity demanded of product L declines. this is line with the law of demand
According to the law of demand, the higher the price, the lower the quantity demanded and the lower the price, the higher the quantity demanded.
Consumers would then shift to the consumption of the close substitute. As a result, there would be an increase in the demand for product J. This would lead to a rightward or outward shift of the demand curve for product J
Normal goods are goods that are goods whose demand increases when income increases and falls when income falls
Since X is a normal good, when income increases, the demand for good X increases. this would shift the demand curve outward
