Is monopolistic competition efficient?

Suppose that a firm produces baseball bats in a monopolistically competitive market. The following graph shows its demand cur $($MR$)$ curve, marginal$-$cost $($MC$)$ curve, and average$-$total$-$cost $($ATC$)$ curve.

Place a black point $($plus symbol$)$ on the graph to indicate the long$-$run monopolistically competitive equilibrium price and quant place a grey point $($star symbol$)$ to indicate the minimum average total cost the firm faces and the quantity associated with that

$(?)$

$$

$$

Because this market is a monopolistically competitive market, you can tell that it is in long$-$run equilibrium by the fact that optimal quantity for each firm. Furthermore, the quantity the firm produces in long$-$run equilibrium is $$ the eff True or False: This indicates that there is a markup on marginal cost in the market for bats.

$$ True
