Susan's rate + Joan's rate = Rate working together
\n" ); document.write( "In words:
\n" ); document.write( "(1 golfball / .016 hrs) + (1 golfball / .025 hrs) = (x golfballs / 1 hrs)
\n" ); document.write( " $\"1%2F.016+%2B+1%2F.025+=+x\"$
\n" ); document.write( "multiply both sides by $\".016%2A.025\"$
\n" ); document.write( " $\".025+%2B+.016+=+%28.016%2A.025%29%2Ax\"$
\n" ); document.write( " $\".0004x+=+.041\"$
\n" ); document.write( " $\"x+=+102.5\"$
\n" ); document.write( "They are recovering 102.5 golfballs per hr working together
\n" ); document.write( "check answer:
\n" ); document.write( " $\"1%2F.016+%2B+1%2F.025+=+x\"$
\n" ); document.write( " $\"62.5+%2B+40+=+102.5\"$
