c. firm's profit-maximizing level of output is less than 100 units

For a certain firm, the 100th unit of output that the firm produces has a marginal revenue of $10 and a marginal cost of $11. It follows that the: a. production of the 100th unit of output increases the firm's profit by $1 b. production of the 100th unit of output increases the firm's average total cost by $1 c. firm's profit-maximizing level of output is less than 100 units d. production of the 110th unit of output must increase the firm's profit by more than $1

C. there are economies of scale in retail sales

Since the 1980s, Wal-Mart stores have appeared in almost every community in America. Wal-Mart buys its goods in large quantities and, therefore, at cheaper prices. Wal-Mart also locates its stores where land prices are low, usually outside of the community business district. Many customers shop at Wal-Mart because of low prices. Local retailers, like the neighborhood drug store, often go out of business because they lose customers. This story demonstrates that: A. consumers do not react to changing prices B. there are diseconomies of scale in retail sales C. there are economies of scale in retail sales D. there are diminishing returns to producing and selling retail goods.
