Answer to Problem 16PPS
The equation is
Explanation of Solution
Given information:
Average American watches of television in a day = 4 hours
Write an equation to represent average number of hours spent watching television by ‘ m’ household members during a period of ‘ d’ day.
Calculation:
The equation can be obtained as
Let,
‘ h’ is the number of hours watched in a household
‘ m’ is the number of members of the household
And ‘ d’ is the number of days
Therefore,
We multiply ‘ m’ and ‘ d’ with 4 hours because American watches 4 hours of television a day
So,
Hence,
The equation is
To find the number of hours that the member of your household watch a television in a week.

Answer to Problem 16PPS
The value
Explanation of Solution
Given information:
Average American watches of television in a day = 4 hours
Assume that the members of your household watch the same amount of television each day as the average American.
Calculation:
The number of hours that the member of your household watch a television in a week can be obtained as
Since we find out
In this question the answer will vary because we assume that the member of your household is 5
Therefore
Hence,
The value
