document.write( "Question 1040269: The telephone company offers two types of service with plan A you can make an unlimited number of a local calls per month for $18.50 with Plan B you pay $6.50 monthly Plus $0.10 for each minute of calls after the first 40 minutes at least how many minutes would you have to use the telephone each month to make Plan A the better option? Please help I don't know how to set this up I'm not good at solving word problems.

This is telling me that plan B is the better choice
\n" ); document.write( "for a certain number of minutes, but after that,
\n" ); document.write( "plan A is better.
\n" ); document.write( "Let \"+n+\" = number of minutes of calls
\n" ); document.write( "with plan B
\n" ); document.write( "-----------------------------------------
\n" ); document.write( "Set up an equation that makes the 2 plans equal
\n" ); document.write( "and then add 1 more minutes to \"+n+\"
\n" ); document.write( "-----------------------------------------
\n" ); document.write( "plan A = plan B
\n" ); document.write( "\"+18.5+=+6.5+%2B+.1%2A%28+n+-+40+%29+\"
\n" ); document.write( "\"+18.5+=+6.5+%2B+.1n+-+4+\"
\n" ); document.write( "\"+12+=+.1n+-+4+\"
\n" ); document.write( "\"+.1n+=+16+\"
\n" ); document.write( "\"+n+=+160+\"
\n" ); document.write( "So this says that after the plans cost the same ( $18.50 )
\n" ); document.write( "per month with both using 160 minutes
\n" ); document.write( "-----------------------
\n" ); document.write( "Now let \"+n+=+161+\" and solve the right side
\n" ); document.write( "\"+6.5+%2B+.1%2A%28+161+-+40+%29+\"
\n" ); document.write( "\"+6.5+%2B+16.1+-+4+\"
\n" ); document.write( "\"+16.1+%2B+2.5+=+18.6+\"
\n" ); document.write( "So, at 161 minutes, plan B becomes more expensive
\n" ); document.write( "than plan A ( plan B costs $18.60 ) \n" ); document.write( "
\n" );
