Table $16-2$

Suppose a monopolist faces the following demand curve:

$\backslash$table$[[\backslash$table$[[$Price$],[($Dollars per unit$)]],\backslash$table$[[$Quantity$],[($Units$)]]],[8,300],[7,400],[6,500],[5,600],[4,700],[3,800],[2,900],[1,1,000]]$

Refer to Table $16-2.$ The monopolist has fixed costs of $$1,000$ and has a constant marginal cost of $$2$ per unit. If the monopolist were able to perfectly price discriminate, how many units would it sell?

a$.500$

b$.900$

c$.400$

d$.4,200$
