5A product is selling nationally, and you devise a spot TV media plan with 75 markets in it. Those 75 markets have a coverage of 79 percent of U. S. TV households. Precisely explain what the 79 percent coverage means?

The meaning of the 79% coverage is that out of 95 potential markets in the US(as calculated below),75 of the markets  can be reached using spot TV media plan.

That is to say the spot TV media has on its platform the largest market share.

However,this does not necessarily guarantees that the product in question will control 79% of the market share as there other factors to consider,for instance consumers' preferences and taste.

Explanation:

95 markets is calculated below:

75 markets=79%

total markets=75/0.79

Total markets=94.93 approximately 95

the investment was $14,174.196

explanation:

a lump sum means that the father of the example made one deposit and leave it be.

we need to know the value of a capital that generated at 4.05% per year during 28 years the sum of $48,613.24

now clearing the formula to solve for capital we got:

and we reach the answer investment = $14,174.20
