Question 1094014
<br>Always think about how you can find the answer to a problem with as little effort as possible.<br>
The third response you got to this question suggests that you should always use the formal algebraic methods in the references she shows to solve problems like this.<br>
The second response shows a standard algebraic solution, confirming the answer given in the first response.<br>
The first response looks at the cost per pound of the cashews, the mixed nuts, and the final mixture, and sees that the cost per pound of the final mixture is exactly halfway between the costs of the two ingredients; and it immediately concludes from that that the amounts of the two ingredients must be equal.<br>
Which method got to the answer with the least amount of work?<br>
Always spend some time thinking about a problem before you start actually trying to solve it, to see if there is an easy path to the solution.
