C - fixed costs; b - costs per bicycle; c + 110 b = 10,900 c + 130 b = 11,600 c = 10,900 - 110 b 10,900 - 110 b + 130 b = 11,600 20 b = 700 b = 700 : 20 = $35 c + 110 * 35 = 10,900 c + 3,850 = 10,900 c = 10,900 - 3,850 c = $7,050 ( daily fixed costs ) Marginal cost is the cost of producing one more unit of goods ( one more bicycle ). Answer: The company`s daily fixed cost is $7,050. The marginal cost per bicycle is $35.
