Question 740885
<br>
The response from the other tutor shows a solution using the standard formal algebraic method for solving this mixture problem.<br>
For any 2-part mixture problem like this one, the problem can be solved informally by a different method; in this problem the solution by this alternative method is very quick and easy because the numbers are "nice".<br>
The short, quick, and easy solution....<br>
Because $1.35 is three-fourths of the way from $1.20 to $1.40, 3/4 of the mixture must be the more expensive flavor.  3/4 of 30 pounds is 22.5 pounds.<br>
ANSWER: 22.5 pounds of the Breakdown flavor, so 30-22.5 = 7.5 pounds of the Nellie flavor<br>
