Question 451898
.
How do I set this problem up:
If a farmer stand owner mixes apple juice and cranberry juice, how much should he charge 
if he mixes 8L of apple juice selling for 45 cents a liter with 10L of cranberry juice selling for $1.08 a liter.

        In the post by @mananth,  the solution is  FATALLY  WRONG  and explained  INCORRECTLY.

        I came to make the job in a right way as it  SHOULD  be done.



<pre>
The total price for the mixture is  0.45*8 + 1.08*10 = 14.40 dollars.


The total volume of the mixture is 8 liters + 10 liters = 18 liters.


Therefore, it is logical to assume that this mixture should be sell at the price 

    {{{14.40/18}}} = 0.8 dollars per liter, or 80 cents per liter.



In compact form, the formula for the price per liter is

    {{{(0.45*8+1.08*10)/(8+10)}}} = 0.80 dollars per liter.    <U>ANSWER</U>

Solved and explained in a right way, &nbsp;as it should be done.


For the peace in your mind, &nbsp;ignore that nonsense in the post by @mananth.
