Answer:
Letter a and b are true.
Step-by-step explanation:
a. In price competition, the seller uses promotion to distinguish its product from competing brands.
- This statement is true because in a price competition, companies' main focus is on matching or exceeding the price charged by competitors, concentrating efforts to become the lowest cost seller among all competitors.
b. The demand curve indicates an inverse relationship between price and quantity demanded.
- This statement is true because it represents the law of demand, that is, the price and demand curve behaves in the opposite way, because as price increases the quantity demanded decreases and as price decreases the quantity demanded increases.
