Let $\"+t+\"$ = time in hrs using the push mower
\n" ); document.write( " $\"+t+-+3.5+\"$ = time in hrs using riding mower
\n" ); document.write( "--------------------------------------------------
\n" ); document.write( " $\"+1%2Ft+%2B+1%2F%28+t+-+3.5+%29+=+1+%2F+2.75+\"$
\n" ); document.write( "Multiply by $\"+t%2A%28+t+-+3.5+%29%2A2.75+\"$
\n" ); document.write( " $\"+2.75%2A%28+t+-+3.5+%29+%2B+2.75t+=+t%2A%28+t+-+3.5+%29+\"$
\n" ); document.write( " $\"+2.75t+-+9.625+%2B+2.75t+=+t%5E2+-+3.5t+\"$
