Suppose Dell is currently selling 250 000

250000 Inspiron laptops per month. A manager at Dellargues: 'The last 10 000

10000 laptops we produced increased our revenue by$8.5 million and our costs by$8.9 millionHowever, because we are making a substantial total profit of$25 million from producing 250 000

250000 laptops, I think we are producing the optimal number oflaptops.'

Briefly whether you agree with themanager's reasoning.
