MATHEMATICSARE TOO NARROW TO BE THE MAIN POINT.

42. b.The simplest way to solve this problem is to(11)(8) or 88 square feet, and again there are twodivide 1 by 1,500, which is 0.0006667. Then,such walls: (88)(2) is 176. Finally, add 144 andcount off two decimal places to arrive at thepercentage, which is 0.06667%. Since the ques-176 to get 320 square feet.
