Lin-Chuan presses his face up against the glass tank at the tropical fish store. There are three types of fish for sale: a bright pink Gourami ($1.20), the nearly invisible Glass fish ($1.80), and the Neon Tetra ($.60) that has an electric blue band. Lin-Chuan steps back and counts his money; he has $6.00. How many different combinations of colorful tropical fish can Lin-Chaun buy with his $6.00?

MAKE AN ORGANIZED LIST
One evening the small, furry, people-like Weebles, Wobbles, and Widgets hurried about in their secret underground caverns. One particular Widget named Wally wandered off too far, and fell in a ravine. Weebles, Wobbles, and Widgets ran over and tried to think of a way to save poor Wally, but no one had a long enough rope. Then Wendell Wobble had an idea: If they formed a furry chain, holding on to each other, maybe they could reach down the 40 inches to Wally. The Weebles were 12 inches high, the Wobbles were 8 inches high, and the Widgets were 4 inches high. How many different combinations of the small creatures would reach 40 inches high?
