of the peanuts to make peanut brittle. The next week, she split the remaining peanuts into 3 bags of trail mix for a hike with friends. How many ounces of peanuts did Diana put in each bag of trail mix

1 answer

Diana used 3/5 of the peanuts to make peanut brittle, which is (3/5) * 16.5 = 9.9 ounces of peanuts.
She had 16.5 - 9.9 = 6.6 ounces of peanuts left.
She split the remaining peanuts into 3 bags of trail mix, so each bag contains 6.6 / 3 = 2.2 ounces of peanuts. Answer: \boxed{2.2}.
