The following graph shows the short-run average total cost curves and the long-run average cost curve for a publishing firm. The five marked quantities indicate points of tangency between each short-run average total cost curve (SRATC) and the long-run average cost curve (LRAC); for example, Q1 marks the point of tangency between SRATC1 and LRAC. The orange point on SPATC3 indicates the firm's current output level in the short run (Q4).
