y, the costlier fertilizer, number of bags
\n" ); document.write( "x, the number of bags of cheaper fertilizer
\n" ); document.write( "-
\n" ); document.write( "Observe that the question is how many bags, but not how many pounds.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "The mixture to result must be $\"28%2F1\"$ dollars per bag.
\n" ); document.write( " $\"%2846%2Ay%2B8%2Ax%29%2F%28x%2By%29=28\"$ \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Accounting for count of bags, $\"x%2By=19\"$ .\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "The \"50-pound bag\" part of the description is just an informative distraction to solving the problem. This problem is the same general type as discussed and solved in the lesson: http://www.algebra.com/my/mixture-price-two-part-both-parts-unknown.lesson?content_action=show_dev, but now that you can plainly see the needed equations for this question, you can simply solve the system for x and y. \n" ); document.write( "
