Answer:
one with few substitutes
Step-by-step explanation:
The higher price markup, the higher the price, the higher the cost to consumers.
If a good has few substitutes, the demand for the good is less elastic. If price is increased, there would be little or no change in quantity demanded and the sellers profit would increase.
If a good has many substitutes, the demand for the good would be more elastic. If price is increased, Quanitity demanded would fall because consumers would shift to cheaper substitutes. Sellers profit would fall.
If demand is very elastic. It means quantity demanded is very sensitive to price. If price is increased, Quanitity demanded would fall by more than the increase in price. Sellers profit would fall.
