Unformatted text preview: Douglass Houghton Workshop, Section 1, Mon 12/5/11 Worksheet Quandries 1. (Adapted from a Winter, 2005 Math 115 exam) Becky nor- mally plays the clarinet and flute, but one day Erin con- vinces her to climb to the top of Burton tower and com- mandeer the carillon, so that Erin can dance to the music.
