Fixawy is a new mobile platform operative in Egypt to search for home service craftsmen. In order to expand its network, the company has decided to develop an aggressive social media marketing campaign on two different social media platforms: Instagram and Facebook. The objective of the company is to reach an exposure level of at least 40% in the city of Cairo and 25% in the city of Alexandria.
Each advertising slot on Instagram costs E£1,500 and has an exposure rating per slot of 5% in the city of Cairo and 2% in the city of Alexandria. Each advertising slot on Facebook costs E£3,500 and has an exposure rating per slot of 6% in the city of Cairo and 4% in the city of Alexandria. The company has decided to use at least 3 slots on Facebook.
Fixawy would like to select the least costly advertising strategy that would meet the desired exposure levels. Formulate and solve this LP problem.
