In the short run, the price curve remains horizontal but can increase or decrease in the short run. The optimal output is where MR=MC (P=MR intersects the MC). If there is no level at which MR=MC, select the highest level of output at which MR>MC.
●AVC, ATC and MC
MC intersects AVC and ATC at the minimum because when MC> AVC for example, them AVC will rise and vice versa.
