I believe the information above is best supported by; the fact that producer surplus will increase if the price rises from $ 8 per unit to $10. This is due to the fact that there is a shortage in the market therefore demand will increase, this results to customers wanting to buy at a higher price than the initial cost, to satisfy their demand and need

Answer: C. The ATC curve eventually slopes upward because average variable cost eventually increases
Explanation:
The Law of Diminishing Marginal Returns causes the Average Total Cost curve to eventually slope upwards because the Average Variable Cost will increase. 
Why? 
At first, with production increasing, a firm will be very efficient at producing a certain good thereby driving the cost down per unit. As time goes on however, the law of Diminishing Marginal Returns comes into play as more is invested into the business. The cost per unit will therefore rise which will lead to the ATC curve going upwards. 
I have included a simple graph to illustrate.

Answer:
40 pounds would be the average inventory
Explanation:
Total Order quantity= 80 pounds
Average inventory level = Order quantity / 2
= 80 pounds / 2
= 40 pounds
Hence, 40 pounds would be the average inventory
