Question

The sales of a certain product after an initial release can be found by the equation

Answer 1

Answer:

Please refer to the attached image in answer area for the graph.

Sales after 8 weeks of release are $855000.

Step-by-step explanation:

Given the equation:

$s = 105t +15$, 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 $\times$ 0 +15 = 15

put t =1, s = 105 $\times$ 1 +15 = 120

put t =2, s = 105 $\times$ 2 + 15 = 210 +15 = 225

put t =3, s = 105 $\times$ 3 + 15 = 315 +15 = 330

put t =4, s = 105 $\times$ 4 + 15 = 420 +15 = 435

Table of values is:

$\begin{center}\begin{tabular}{ c c } t & s\\ 0 & 15\\ 1 & 120 \\ 2 & 225 \\ 3 & 330 \\ 4 & 435\end{tabular}\end{center}$

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 $855000.
