The Standard model sells for $235 and the Enhanced model sells for $305. If Yolanda sold a total of 11 units and took in $3,005, how many of the Enhanced model did she sell?
\n" ); document.write( "--------------------------
\n" ); document.write( "Equation:
\n" ); document.write( "Quantity:: s + e = 11
\n" ); document.write( "Value Eq::235s + 305e = 3005
\n" ); document.write( "--------------------------------------
\n" ); document.write( "Modify for elimination:
\n" ); document.write( "235s + 235e = 235*11
\n" ); document.write( "235s + 305e = 3005
\n" ); document.write( "------
\n" ); document.write( "Subtract and solve for \"e\"::
\n" ); document.write( "70e = 420
\n" ); document.write( "e = 6 (# of enhanced model's sold)
\n" ); document.write( "------------------------------------
