Calculate his (short-run) average total cost (ATC) for quantities of 50, 100, and 150 and sketch his ATC curve given the values you calculated.
a) ATC(50) = $30; ATC(100) = $25; ATC(150) = $23
b) ATC(50) = $20; ATC(100) = $15; ATC(150) = $13
c) ATC(50) = $25; ATC(100) = $20; ATC(150) = $18
d) ATC(50) = $15; ATC(100) = $10; ATC(150) = $8
