To find the average variable cost per car, we need to divide the total variable cost (which is equal to total cost - total fixed cost) by the number of cars repaired. Total fixed cost = $40 + $20 = $60 Total variable cost = $4s² * 10 = $4120 Therefore, Average variable cost per car = ($4120 - $60) / 10 = $4060 / 10 = $406 But since the answer choices are given in dollars, we need to convert this amount to dollars. $406 = $4.06 Therefore, the average variable cost per car is $80. Thus, the correct answer is D.
