Hi there,
\n" ); document.write( "Set up two formulae:
\n" ); document.write( "For Keisha 1st Plan:
\n" ); document.write( "$40 + n(0.16) [n = no. of miles driven.]
\n" ); document.write( "For Keisha's 2nd Plan:
\n" ); document.write( "$49 + n(0.11)
\n" ); document.write( "Make them equal one another:
\n" ); document.write( "$40 + n(0.16) = 49 + n(0.11)
\n" ); document.write( "Collect like terms:
\n" ); document.write( "n(0.16) - n(0.11) = 49 - 40
\n" ); document.write( "n(0.05) = 9
\n" ); document.write( "n = 9/0.05
\n" ); document.write( "n = 180
\n" ); document.write( "Therefore 180 has to be driven
\n" ); document.write( "before the plans cost the same.
\n" ); document.write( "The cost is $68.80
\n" ); document.write( "Hope this helps:-)
\n" ); document.write( "
\n" );
