Answer to Question 1

Firms must decide how much to produce and supply in the output market, which technology to use, and how much of each input to demand. These three decisions are interrelated because the decision of how much to supply depends on costs of production, which in turn depends upon the technology used and the amount of inputs used. The use of inputs will depend on the amount of output produced.

Answer to Question 2

The firm is incurring an economic loss. Its price (3.75) is less than its average total cost (4.50). In order to determine if the firm should continue operating in the short run, we must compare the firm's price with its average variable cost. As long as the price is greater than average variable cost, the firm should continue to operate.
