Question 1146900
====================
How many pounds of chamomile tea that costs $18.20 per pound must be mixed with 14 lb of orange tea that costs $12.26 per pound to make a mixture that costs $14.42 per pound? 
=====================


c, pounds of Chamomile tea


{{{18.2c+12.26*14=14.42*(c+14)}}}
-
{{{18.2c+12.26*14=14.42c+14.26*14}}}
{{{18.2c-14.42c=14.26*14-12.26*14}}}
{{{(18.2-14.42)c=14(14.26-12.26)}}}

{{{c=14((14.26-12.26)/(18.2-14.42))}}}--------compute this.


Your other two questions are the same kind but different units and numbers.
