mamaluj [8]

Answer: She would have 16 bags of trail mix.

Step-by-step explanation: Since one bag of trail mix contains 1/8 of a pound. You need to add how much it will take to make 2 pounds. So you keep adding 1/8 but the denominator stays the same each time you add. So it will look like this: 1/8 + 1/8 = 2/8 and you keep repeating it until you get 8/8 which equals 1 pound. Then you add 1/8 until you get 8/8 again. So 8 + 8 = 16.
