Chapter 1.3, Problem 110E

(a)

To determine

To calculate: The linear model for the cost (in thousands of dollars) of a super bowl ad y as a function of the number of years t since $1980$ using the data of $1980$ and $2000$ if the table and the graph representing the increasing cost of a $30$ seconds television ad with the years as,

Year	$1970$	$1980$	$1990$	$2000$	$2010$
Cost $\left(\$1,000\right)$	$78$	$222$	$700$	$2,100$	$2,950$

The graph is;

(b)

To determine

To calculate: The linear model for the cost (in thousands of dollars) of a super bowl ad y as a function of the number of years t since $1980$ using the data of $2000$ and $2010$ if the table and the graph representing the increasing cost of a $30$ seconds television ad with the years as,

Year	$1970$	$1980$	$1990$	$2000$	$2010$
Cost $\left(\$1,000\right)$	$78$	$222$	$700$	$2,100$	$2,950$

(c)

To determine

To calculate: The piecewise linear model for the cost of a Super Bowl ad during $1980-2010$ using the models obtained in part (a) and part (b).

(d)

To determine

To calculate: The cost of Super Bowl ad in $1992$ by using the model obtained in part (c) and interpret whether the answer is in the rough agreement with the graph which is as follows:
