Please help. This is due at midnight and I can't figure it out.

(1 point) A hardware store will run an advertising campaign using radio and newspaper. Every dollar spent on radio advertising will reach 80 people in the "Under $30,000" market, and 60 people in the "Over $30,000" market. Every dollar spent on newspaper advertising will reach 110 people in the "Under $30,000" market, and 30 people in the "Over $30,000" market. If the store wants to reach at least 219,000 people in the "Under $30,000" market and 240,000 people in the "Over $30,000" market, how much should it spend on each type of advertising to minimize the cost? Minimum amount spent on advertising (in dollars): Dollars spent on radio advertising: Dollars spent on newspaper advertising
