Question

The annual sales (in billions of dollars) of global positioning system (GPS) equipment from the year 2000 through 2006 follow. (Sales for 2004–2006 were projections.) Here x=0 corresponds to 2000.

$\begin{array}{lccccccc} \hline \text { Annual Sales, } y & 7.9 & 9.6 & 11.5 & 13.3 & 15.2 & 17 & 18.8 \\ \hline \text { Year, } x & 0 & 1 & 2 & 3 & 4 & 5 & 6 \\ \hline \end{array}$

Use the equation found in part (c) to estimate the annual sales of GPS equipment for 2005. Compare this figure with the projected sales for that year.

Step 1

1 of 2If $y=1.82x+7.9$ and $x=5$ then

$\begin{aligned} y&=1.82\cdot 5+7.9=17 \end{aligned}$

which is the right annual sale for $2005$.
