Scenario 1

1
Suppose a cell phone manufacturer currently sells 20,000 cell phones per week and makes a profit of $5,000 per week. A
manager at the plant observes, "Although the last 3,000 cell phones we produced and sold increased our revenue by $6,000
and our costs by $6,700, we are still making an overall profit of $5,000 per week so I think we're on the right track. We are
producing the optimal number of cell phones."

additional repair, which will cost another $400, in order to make the boat worth $800 to potential buyers.
He
can sell the boat as it is now for $300.
