$\"lung+capacity=0.041h-0.018a-2.69\"$
\n" ); document.write( " $\"height=h=160\"$
\n" ); document.write( " $\"age=a=50\"$
\n" ); document.write( "Substitute in the equation at the top the values given for $\"a\"$ and $\"h\"$
\n" ); document.write( " $\"lung+capacity=0.041%2A160-0.018%2A50-2.69=6.56-0.9-2.69=2.97\"$
\n" ); document.write( "The lung capacity of that woman is estimated at 2.97 liters.
