Individual Excel Solver Computer Project
Eddie Kelly is running for reelection as mayor of a small town in Vaal. Jessica Martinez,
Kelly’s campaign manager during this election, is planning the marketing campaign, and
there is some stiff competition. Martinez has selected four ways to advertise: television
ads, radio ads, billboards, and newspaper ads. The costs of these, the audience
reached by each type of ad, and the maximum number of each is shown in the table
below:

In addition, Martinez has decided that there should be at least six ads on TV or radio or
some combination of those two. The amount spent on billboards and newspapers
together must not exceed the amount spent on TV ads. While fundraising is continuing,
the monthly budget for advertising has been set at R150 000.
