Final answer:
The equilibrium price for T-shirts is determined by the interaction of demand and supply in the market.
Step-by-step explanation:
The equilibrium price for T-shirts is the price at which the quantity demanded by consumers is equal to the quantity supplied by producers. In this case, the question does not provide enough information to determine the equilibrium price. The options given are $5, $10, and $25, but without knowing the demand and supply conditions, we cannot determine the specific equilibrium price.
Equilibrium price is determined through the interaction of demand and supply in a market. If the demand for T-shirts is high and the supply is low, the equilibrium price may be higher. On the other hand, if the demand is low and the supply is high, the equilibrium price may be lower.
Therefore, without additional information about the demand and supply for T-shirts, we cannot determine the exact equilibrium price.
