Question and rationale: The question is: Every time Janet folds her blanket its thickness doubles. If it starts out 3 inches thick, how thick will it be after 4 foldings?
Step-by-step reasoning process: First find how thick the blanket will be after 1 folding: 3 inches * 2 = 6 inches. Then find how thick the blanket will be after 2 foldings: 6 inches * 2 = 12 inches. Then find how thick the blanket will be after 3 foldings: 12 inches * 2 = 24 inches. Then find how thick the blanket will be after 4 foldings: 24 inches * 2 = 48 inches.
