The advertising director for Diversey Paint as well as Supply a chain of four retail stores on Chicago's North Side is considering two media possibilities. One strategy is for a series of half-page ads in the Sunday Chicago Tribune newspaper as well as the other is for advertising time on Chicago TV. The stores are expanding their lines of do- it- yourself tools as well as the advertising director is interested in an exposure level of at least 40% within the city's neighbourhoods as well as 60% in northwest suburban areas. The TV viewing time under consideration has an experience rating per spot of 5% in city homes and 3% in the northwest suburbs. The Sunday newspaper has corresponding experience rates of 4% and 3% per ad. The cost of a half-page Tribune advertisement is $ 925; a television spot costs $ 2,000. Diversey Paint would like to select the smallest costly advertising strategy that would meet anticipated exposure levels
