(2) Company R's annual profit has increased by $7,500 each year since 1985.

Statement 1: In 1985, profit was $212,000 and 1989 profit was 242,000. So each year profit was (242,000-212000)/4 = 7500. So it is sufficient to find the profit in 1991 by adding 15000 to 242,000.

so suffi.

Statement 2: insuffi.

So answer : A
