Consider the following data:

$$\begin{array}{llr} \hline \text { Variable selling and administrative costs per unit } & \$ 7.00 \\ \text { Total fixed selling and administrative costs } & \$ 810,000 \\ \text { Total fixed manufacturing costs } & \$ 500,000 \\ \text { Variable manufacturing costs per unit } & \$ 12.00 \\ \text { Units produced and sold } & 100,000 \\ \hline \end{array}$$

Compute the following per unit of product: (b) full manufacturing cost

The resident population of Wisconsin (in thousands) was 5655 in 2009 and 5743 in 2013. Assume that the relationship between the population y and the year t is linear. Let t = 0 represent 2000. (a) Write a linear model for the data. What is the slope and what does it tell you about the population?
(b) Use the model to estimate the population in 2011.
(c) Use your school's library, the Internet, or some other .reference source to find the actual population in 2011. How close was your estimate?
(d) Do you think your model could be used to predict the population in 2018? Explain.

Charlie and Aisha built a small rocket and launched it from their backyard. The rocket fell to the ground 10 s after it launched. The height h, in feet of the rocket relative to the ground at time t seconds can be modeled by the function shown.

$$h(t)=at^2+bt+c$$

Construct Arguments Charlie believes that the function

$$h(t) = -16t^2 + 160t$$

models the height of the rocket with respect to time. Do you agree? Explain your reasoning and indicate the domain of function.
