Answer:
Please refer to the attached image in answer area for the graph.
Sales after 8 weeks of release are <em>$855000</em>.
Step-by-step explanation:
Given the equation:
, where
s is the total sales in thousands and
t is the time in weeks
First of all, let us create table of values:
put t =0, s = 105
0 +15 = 15
put t =1, s = 105
1 +15 = 120
put t =2, s = 105
2 + 15 = 210 +15 = 225
put t =3, s = 105
3 + 15 = 315 +15 = 330
put t =4, s = 105
4 + 15 = 420 +15 = 435
Table of values is:
![\begin{center}\begin{tabular}{ c c } t & s\\ 0 & 15\\ 1 & 120 \\ 2 & 225 \\ 3 & 330 \\ 4 & 435\end{tabular}\end{center}](https://tex.z-dn.net/?f=%5Cbegin%7Bcenter%7D%5Cbegin%7Btabular%7D%7B%20c%20c%20%7D%20t%20%26%20s%5C%5C%200%20%26%2015%5C%5C%201%20%26%20120%20%5C%5C%20%20%202%20%26%20225%20%5C%5C%20%20%203%20%26%20330%20%5C%5C%20%20%204%20%26%20435%5Cend%7Btabular%7D%5Cend%7Bcenter%7D)
Now, when we plot these points, we get a graph as shown in the attached answer image.
t is plotted on x axis and s on y axis.
The graph is very near to y axis because smaller values of t, values of y are larger.
Sales after 8 weeks of release are <em>$855000</em>.
