Question

A hardware store will run an advertising campaign using radio and newspaper. Every dollar spent on radio advertising will reach 60 people in the "Under $30,000" market, and 50 people in the "Over $30,000" market. Every dollar spent on newspaper advertising will reach 80 people in the "Under $30,000" market, and 30 people in the "Over $30,000" market. If the store wants to reach at least 570,000 people in the "Under $30,000" market and 600,000 people in the "Over $30,000" market, how much should it spend on each type of advertising to minimize the cost?
