To find: the optimal amount that should be spent on each type of ad, and the optimal total audience.
Answer to Problem 45E
The maximum amount spend for television ad is $0.
Maximum amount spend for paper ad is $1000000.
Maximum viewer is 250 million.
Explanation of Solution
Given:
A company budgets a maximum of $1000000 for national advertising of an allergy medication. Each TV ad costs $100000 and each one page newspaper ad costs $20000. Each TV ad is expected to be viewed by 20 million views, and each newspaper ad is expected to be seen by 5 million readers. The company’s marketing department recommends that at most 80% of the budget be spent on TV ads.
Calculation:
Let
And
Total budget is $1000000
Each minute of television ad cost $100000 and each one page newspaper ad cost $20000, that is
Each television ad is viewed by 20 million viewers and paper ad is viewed by 5 million
Objective function in millions is
At most 80% of the advertising budget should be spent for television ad
Now the given data as a linear programming problem is
Objective function:
Constraints:
First draw the region corresponding to the system of constraints
Here vertices of the region are
Find the objective function at each vertex
Here maximum value 250 is occurred for
The amount spend for television ad is
The amount spend for paper ad is
Here the maximum amount spend for television ad is $0.
Maximum amount spend for paper ad is $1000000.
Maximum viewer is 250 million.
