Let $\"+x+\"$ = cost of 1 cupcake
\n" ); document.write( "given:
\n" ); document.write( " $\"+3x+%2B+1.6+=+7x+\"$
\n" ); document.write( " $\"+4x+=+1.6+\"$
\n" ); document.write( " $\"+x+=+.4+\"$
\n" ); document.write( "and
\n" ); document.write( " $\"+3x+=+1.2+\"$
\n" ); document.write( " $\"+2%2A1.6+=+3.2+\"$
\n" ); document.write( "------------------
\n" ); document.write( " $\"+1.2+%2B+3.2+=+4.4+\"$
\n" ); document.write( "3 cupcakes and 2 teas cost $4.40
\n" ); document.write( "-------------------------------
\n" ); document.write( "check:
\n" ); document.write( " $\"+3x+%2B+1.6+=+7x+\"$
\n" ); document.write( " $\"+1.2+%2B+1.6+=+7%2A.4+\"$
