Question 800424
Think how to account for cost and how to account for pounds, each of these separately.


Let g = how many pounds of the Gazebo coffee to use.


COST:  {{{(12.60)(29)+13.70g=(29+g)(13.17)}}}


Set up that way, only the one equation is necessary.  You can try to account for poundage, but you'll have an unnecessary variable.  This COST equation is cost of the two parts on the left being equal to the cost of the mixture expected, on the right.   SOLVE FOR g.
