If l(r) = 400r, find: l(0.11), l(0.12), and l(0.15)
\n" ); document.write( "Replace the r in the function with the values given in the parentheses.
\n" ); document.write( "l(0.11) = 400(0.11) = 44
\n" ); document.write( "l(0.12) = 400(0.12) = 48
\n" ); document.write( "l(0.15) = 400(0.15) = 60
\n" ); document.write( "
\n" );
