150 IS WHAT PERCENT OF 750?
\n" ); document.write( "Use the formula:
\n" ); document.write( "Part/Whole = Percent/100
\n" ); document.write( "Plug-in the values and solve for the x-term:
\n" ); document.write( "150/750=x/100
\n" ); document.write( "(150)(100)=(750)(x)
\n" ); document.write( "15000=750x
\n" ); document.write( "15000/750=x
\n" ); document.write( "20=x
\n" ); document.write( "20%

\n" ); document.write( "-1.6=2x
\n" ); document.write( "-1.6/2=x

\n" ); document.write( "0.4X-1.6=2.4X
\n" ); document.write( "0.4(-0.8)-1.6=2.4(-0.8)
\n" ); document.write( "-1.92=-1.92 [checks out]
