Price will increase
Price of related goods fall into two categories: substitutes and complements. Complements are when a price decrease in one good increases the demand of another good. Substitutes are when a price decrease in one good decreases the demand for another good.
If goods A and B are substitutes, a decrease in the price of good B will likely lead to a decrease in the demand for good A. Consumers will find good B more attractive due to its lower price, leading them to purchase more of B instead of A. Consequently, the demand curve for good A shifts leftward, potentially reducing its equilibrium price and quantity.
Substitutes and complements is the fact that a change in price of one of the goods has an impact on the demand for the other good. For substitutes, an increase in the price of one of the goods will increase demand for the substitute good. (It's probably not surprising that an increase in the price of Coke would increase the demand for Pepsi as some consumers switch over from Coke to Pepsi.) It's also the case that a decrease in the price of one of the goods will decrease demand for the substitute good.

Relationship of good price to price of substitutes and complements: 1) Substitutes: as the price of substitutes for a good falls, the price of a good must fall in order to maintain demand. 2) Complements: as the price of complements falls, the price of a good can increase and still maintain the same level of demand.
Elastic goods usually have many substitutes, so changes in price will decrease demand. Inelastic goods, on the other hand, have very few substitutes, so demand isn't generally affected by price change.
When two goods are complements, a decrease in the price of one good will typically increase the demand for the other good. Conversely, an increase in the price of one good will usually decrease the demand for the other good. This is because the two goods are often consumed together, so a change in the price of one affects the demand for the other.
Price demand refers to the relationship between the price of a good and the quantity demanded by consumers; typically, as prices decrease, demand increases, and vice versa. Income demand indicates how the quantity demanded of a good changes as consumer income changes, with normal goods seeing increased demand as income rises, while inferior goods may see decreased demand. Cross demand measures how the quantity demanded of one good responds to changes in the price of another good, where substitutes see an increase in demand when the price of the alternative rises, and complements see a decrease in demand when the price of the related good rises.
If two goods are complementary, an increase in the price of one good will lead to a decrease in the demand for the other good. This is because consumers typically use these goods together, so if one becomes more expensive, they are less likely to purchase both. Conversely, a decrease in the price of one good can increase the demand for both goods.
Elasticity is the percentage change in one variable resulting from a percentage change in another variable. Thus, the price elasticity of demand is the percentage change in quantity demanded of a good resulting from a percent change in its price. Elastic demand means that the percentage change in quantity demanded of the good is greater than the percentage increase in price. This means that the demand for a good is very sensitive relative to price. Therefore, if the price increases by one dollar the quantity demanded for that good will decrease by a lot and if the price decreases by one dollar the quantity demanded for that good will increase by a lot. The determinants of price elasticity of demand are: substitutes of the good, percentage of income the good's price, and the need of the good. Substitutes are other goods that have the same or similar function to the particular good; if there are many substitutes then the price will be elastic in which the primary good becomes too expensive consumers will switch their demand to a close substitute, and if there are not many substitutes the price will be inelastic in which the primary good becomes very expensive consumers will have to buy that good no matter what. If the price of the good is a large percent of the consumer's income the elasticity of demand will be high, since the consumer will not want to spend the majority of their income on one good. If the good is a necessity, for example food, then people will have to buy it no matter the price therefore it will be very inelastic. If the good is a luxury good like a yacht then the demand elasticity will be very elastic.
The demand for perfectly elastic goods in the market is determined by factors such as the availability of close substitutes, consumer preferences, and the price of the good. When there are many substitutes available, consumers are more likely to switch to a different product if the price changes, leading to a perfectly elastic demand curve.
