There are 435 seats in a​ nation's House of Representatives. The number of representatives per state is calculated using a statistical formula determined by​ law, but allocation is roughly proportionate to population. In​ 2010, the​ nation's population was estimated to be 309.1 million. The​ state's population was estimated at 26.1 million. How many representatives would you expect to be assigned to the​ state?

The Sea Wharf Restaurant would like to determine the best way to allocate a monthly advertising budget of $1,000 between newspaper advertising and radio advertising. Management decided that at least 25% of the budget must be spent on each type of media and that the amount of money spent on local newspaper advertising must be at least two and a half times the amount spent on radio advertising. A marketing consultant developed an index that measures audience exposure per dollar of advertising on a scale from 0 to 100, with higher values implying greater audience exposure. If the value of the index for local newspaper advertising is 50 and the value of the index for spot radio advertising is 80, how should the restaurant allocate its advertising budget to maximize the value of total audience exposure? (a) Formulate a linear programming model that can be used to determine how the restaurant should allocate its advertising budget in order to maximize the value of total audience exposure. If…
