decrease
If the price of a firm's variable input increases, The firm will -- its level of production.

decrease
In a perfectly competitive industry, the market price of the product is $12. A firm produces at a level of output where average total cost is $16, marginal cost is $16, and average variable cost is $8. To maximize its profit, the firm should -- output but keep producing

In the short run, a perfectly competitive firm should shut down whenever minimum average -- cost -- price
greater, variable
In the short run, if a firm produces the level of output at which marginal revenue is equal to marginal cost but price is less than average total cost, the firm will continue to operate if price is -- than its average -- cost
