I got a these questions wrong on an assignment and I need some help with the answers that are labelled incorrect.

The marginal costs (MC), average variable costs (AVC), and average total costs (ATC) for a firm are shown in the figure below. Instructions: Use the tool provided 'Profit/Loss' to illustrate the area of profit (or loss) that occurs at the profit-maximizing level of output. Drag the points to move or resize.

Given that the market is in longrun equilibrium, the market price is: $ 21.50 0- For a perfectly competitive industry with identical firms, the longrun industry supply curve is: perfectly elastic. horizontal. 9 based on minimum average costs. All of these are characteristics of the longrun supply curve. Which of the following best describes the longrun supply curve? A horizontal line at minimum ATC a An upwardsloping line A horizontal line at minimum AVC A vertical line at minimum AVC A vertical line at minimum ATC
