Give the step-by-step reasoning process and then the final answer. Alissa used discarded paper to make notepads for her friends. She would fold 5 pieces of letter-size paper 3 times then cut along the edges to form smaller note papers. She would then stack these smaller note papers and staple them together. How long would 1 notepad last if someone wrote 10 notes per day?

Alissa folding it 3 times makes 2 × 2 × 2 = 8 pieces of note - size paper per letter - size paper. So 5 pieces of letter - size paper make 5 × 8 = 40 pieces of note - size paper. 1 note pad would last 40 ÷ 10 = 4 days if someone wrote 10 notes a day.
The final answer: 4.
