Algebra An independent political candidate wants to run both TV and radio advertisements.
Suppose that each minute of TV advertising is expected to reach 15,000 people, and each minute of radio advertising is expected to reach 7,000 people. Each minute of TV advertising costs $1,600 and each minute of radio advertising costs $600. The candidate has a maximum of $60,000 to spend on advertising. She wants to maximise the number of people that her advertising reaches, but doesn't want to oversaturate the electorate, so wants the total number of minutes to be no more than 80.
