Suppose Apple has started production on a new virtual reality headset. Unsure of how much to charge for the headset, they hire a consulting firm to estimate demand. The consulting firm finds that demand is described by Q = 10,000 - 5P (and inverse demand is described by P = 2,000 - 0.2Q), where Q indicates quantity of headsets sold and P denotes price in US dollars. If the marginal cost of producing the headsets is constant at $400 what price should they charge?

A) $1,000

B) $1,600

C) $1,200

D) $1,500

E) $2,000
