If each of the four subsidiaries of Corporation R has been granted a line of credit of $700,000 and each of the other subsidiaries of the Corporation R has been granted a line of credit of $112,000, what is the average (arithmetic mean) line of credit granted to a subsidiary of the Corporation R? (A) $1,568,000 (B) $448,000 (C) $406,000 (D) $313,000 (E) $116,000 The total credit for the four subsidiaries (4*700,000) is $ 2,800,000 and the total credit for the three subsidiaries is (3*112,000) $336,000. The combined total of credit for all the seven subsidiaries is $3,136,000. So, their combined average is $3,136,000/7 = $448,000. So, the answer is (B).
