O True C FalseBased on the table below, what does total cost equal at 24 units of output? Based on the table below, what does total variable cost equal at 25 units of output? 0 There is not sufficient information to draw a conclusion. If Willie's fixed costs total $500 and variable costs total $80 at 100 units of output, what would his average total costs equal
