At the level of input and output where marginal revenue is equal to marginal cost, total profit will always be positive.

Continuing the example from the previous question, if the cost of silage decreases to $0.05/lb while the cost of grain remains unchanged:

Based on the table introduced in question #12, what is the value for MPP that should appear in cell **B**?

Based on the table introduced in question #12, what is the value for MPP that should appear in cell **C**?

The table below gives combinations of silage and grain (inputs) that will produce 20,000 pounds of milk per year (output). Ration Number  Grain (lbs.)  Silage (lbs.)  Substitution Ratio  1 4,000 11,628 XXX  2 4,500 9,880 3.50 3 5,000 8,322 3.12 4 5,500 6,935 2.77 5 6,000 5,700 2.47 6 6,500 4,598 2.20 If grain costs $0.15/lb and silage costs $0.06/lb, what is the least-cost combination of grain and silage for the feed ration?

Marginal physical product must always be greater than average physical product.

You have a 5-acre organic farm that produces vegetables to sell at the local farmer’s market. You pay a local high school student $12 an hour to help you, mainly with weeding. You need to decide how to allocate your employee’s time to maximize profits. Below is a table showing the marginal value product of each successive hour of weeding for two crops.  Hours weeding Beets Potatoes First hour $20 $24 Second hour $15 $22 Third hour $10 $19 Fourth hour $5 $14 If the employee can work for up to 4 hours, how should those hours be spent to maximize the farm’s profit?
