Question 1203426
<br>
Here is an alternative to the standard formal algebraic solution for solving 2-part mixture problems like the one shown by the other tutor.<br>
For this problem, it is not an efficient method; but for many similar problems it is faster and easier than formal algebra.<br>
The fraction of the mixture that is 60% peanuts is 16/(14+16) = 16/30 = 8/15.<br>
That means the percentage of peanuts in the mixture is 8/15 of the way from 15% to 60%.<br>
From 15% to 60% is a difference of 45%; 8/15 of 45% is 24%.  The percentage of peanuts in the mixture is 15%+24% = 39%.<br>
ANSWER: 39%<br>
