A developer sold 20 percent fewer houses in October than in September and 50 percent more houses in November than in October. If the developer sold H houses in September, which of the following represents the number of houses the developer sold in November?

(A) 0.3H
(B) 0.7H
(C) 1.2H
(D) 3H
(E) 7H

September = H

A developer sold 20 percent fewer houses in October than in September:

October = 0.8H

... and 50 percent more houses in November than in October:

November = 1.5 * 0.8H = 1.2H

Answer: C.
