Solve the following problem using system of equations.
\n" ); document.write( "How many pounds of nuts selling for $6 per lb and raisins selling for $3 per lb should a person combine to obtain 180 lb of a trail mix selling for $4 per lb.
\n" ); document.write( "------------
\n" ); document.write( "Equations:
\n" ); document.write( "Quantity:: s + t = 180 lb
\n" ); document.write( "Value::: 6s +3t = 4*180 dollars
\n" ); document.write( "----------------------------
\n" ); document.write( "Modify::
\n" ); document.write( "s + t = 180
\n" ); document.write( "2s+ t = 240
\n" ); document.write( "----
\n" ); document.write( "Subtract and solve for \"s\":
\n" ); document.write( "s = 60 lb (amt. of $6 nuts needed)
\n" ); document.write( "----
\n" ); document.write( "t = 180-60 = 120 (amt. of $3 nuts needed)
\n" ); document.write( "-------------
