Five identical scales are labeled from 1 to 5. We know that for each M = 1,2,3,4,5 the scale with label M adds M kg to each weight. The labels are then removed and the scaled are shuffled. A bag is weighed on each scale, producing the following measures in kg:9,10,11,12,13. How many kg does it weigh? (A) 7 (B) 8 (C) 9 (D) 10 (E) 11

The first Batman movie was made over 50 years ago in 1966. Över the years, Batman has been played on screen by a number of actors and even by a Lego figure in the Lego Batman movies. In the original comic books, Batman was 188 centimeters tall (about 6'2") and weighed 95 kilograms (about 210 pounds). The article "50 Years of Batman on Film: How Has His Physique Changed?"t included the heights and weights of all of the onscreen Batmen in the table below.

Solve the problem. At the Jumping Jack cookie factory, quality assurance inspectors remove broken or otherwise defective cookies from a moving conveyor belt prior to packaging. Based on past studies, the plant manager knows that the inspectors eliminate 98% of the defective cookies at a conveyor belt speed of 9 feet per minute. As the belt speed increases, the factory can produce more cookies per hour, but at the cost of lower quality of the packaged product. Inspectors collect only 60% of defective cookies at a belt speed of 18 feet per minute.
