This document presents an optimization problem to maximize advertising revenue. The objective is to maximize revenue (E) from advertising on TV, radio, and newspapers based on time of day. There are constraints on the minimum and maximum amounts that can be spent in each time period and medium. The optimal values that maximize revenue while satisfying the constraints are: 10 units of TV ads in the first 10 minutes, 6.35 units in later TV periods, 15 units of early radio ads, 18 units of later radio ads, 16.5 units of early newspaper ads, and 0 units of later newspaper ads. The maximum revenue (E) achieved under these optimal values is 2149.25.
