Final answer:
The question seeks information on Alfred's production quantity, pricing, and profit or loss at a market equilibrium price of $12.50, but there is not enough information provided to accurately answer.
Step-by-step explanation:
The question posed relates to understanding market equilibrium, production decisions, and profit calculation in a business context. Unfortunately, without additional information such as Alfred's cost structure, the supply equation, or demand at the price of $12.50 for basketballs, it is impossible to determine how many basketballs Alfred will produce, the price he will charge, or the profit or loss he might incur.
For accurate assessment in economics, factors such as cost of production, supply function, and demand function are crucial. Therefore, we cannot provide a definite answer to the question about how many basketballs Alfred will produce, what price he will charge, or his profit or loss at the market equilibrium price of $12.50 without this information.
