Answer:
Marginal cost is greater than its average cost.
Step-by-step explanation:
Given that,
Cost of producing 500 graphing calculators = $35,000
Cost of producing 501 graphing calculators =$35,080
Therefore,
The marginal cost = Cost of 501 graphing calculator - Cost of 500 graphing calculator
= $35,080 - $35,000
= $80
Average cost:
= $35,000 ÷ 500
= $70
Therefore, the marginal cost is greater than its average cost.
