Answer:
The average cost of production will fall by $0.05 per unit, from $30.23 to $30.18
Step-by-step explanation:
The marginal cost is the cost of producing an additional unit.
The marginal cost of 15th unit is $29.5 which means it will cost $29.5 to produce the 15th unit.
If the average cost per unit for the 14 units is 30.23, then total cost of producing these 14 units will b, 30.23 * 14 = $423.22
The total cost of producing 15 units will b, 423.22 + 29.5 = $452.72
The new average cost at production of 15 units is, 452.72 / 15 = $30.18
Thus, as a result of adding the 15th unit, the average cost per unit fell by $0.05 from $30.23 to $30.18
