An advertising agency proposes two media plans for a product launch targeting a market of 500,000 people. Plan A: - TV reaches 40 % of the market, cost ₦(2,500,000), frequency 3 exposures per viewer. - Radio reaches 30 % of the market, cost ₦(1,200,000), frequency 2 exposures per listener. - Overlap between TV and radio audiences is 10 % of the market; overlapping viewers receive the sum of the two frequencies.
