can you explain how they got these answers thank you!

Answer the question on the basis of the following cost data for a firm that is selling in a purely competitive market.

Explanation / Answer

109.the law of diminishing returns- as the marginal cost is increaing with each increase in unit

110. $150; $300- fixed cost = 6*25=150, total cost = 6*50 = 300

111.$60; $210.- variable cost = 3*20 = 60, total cost = 3*70 = 210

112.$150, zero, and $150, respectively.- this is because we are given marginal cost = 25, which means at 0 unit of output total cost was 150 and total cost comprises of fixed cost and variable cost, at 0 units there will be no variable cost hence fixed cost = 150

113.9 units at an economic profit of $281.97.- profit = 87-55.67 = 31.33*9 = 281.97

114.8 units at an economic profit of $130.72. -profit = 68.10-51.76 = 16.34*8 = 130.72

115.6 units at a loss of $90.- loss = 35-50 = -15*6 = -90

116.4 units at a loss of $138.- loss = 24-58.5 = -34.5*4 = -138

117.0 units at a loss of $150. - loss = 150 which is the fixed cost
