Problema Solution
A 21 oz. bag of mixed nuts contains 29% peanuts. To make this mixture product they combine a mix of nuts which contains 35% peanuts and a mix of nuts which contain 25% peanuts. How much of each do they need to use?
Answer provided by our tutors
35% peanuts: x
25% peanuts: 21-x
So
35%x + 25%(21-x)= 21*29%
x = 8.4
So there are 8.4 oz of 35% peanuts and 12.6 oz of 25% peanuts
