Use this scenario: A wireless carrier offers the following plans that a person is considering. The Family Plan: $\$ 90 dollars monthly fee, unlimited talk and text on up to 8 lines, and data charges of $\$ 40 dollars for each device for up to $2 \mathrm{GB}$ of data per device. The Mobile Share Plan: \$ 120 dollars monthly fee for up to 10 devices, unlimited talk and text for all the lines, and data charges of \$ 35 dollars for each device up to a shared total of $10 \mathrm{GB}$ of data. Use $P$ for the number of devices that need data plans as part of their cost.Find the model of the total cost of the Mobile Share Plan.Assuming they stay under their data limit, find the number of devices that would make the two plans equal in cost.

Clock Pendulum The pendulum in a grandfather clock makes one complete swing every 2 s. The maximum angle that the pendulum makes with respect to its rest position is $10^{\circ} .$ We know from physical principles that the angle $\theta$ between the pendulum and its rest position changes in simple harmonic fashion. Find an equation that describes the size of the angle $\theta$ as a function of time. (Take $t=0$ to be a time when the pendulum is vertical.)

Advertising Effect. Great Grains Cereal Company is about to market a new low-carbohydrate cereal in a city of 5,000,000 people. They plan an advertising campaign that they think will induce 30% of the people to buy the product. They estimate that if those people like the product, they will induce 30,  30,  5,000,000 more to buy the product, and those will induce 30,  30, 30,  5,000,000, and so on. In all, how many people will buy the product as a result of the advertising campaign? What percentage of the population is this?

Landing Speed The function $V=\sqrt{1.496 w}$ expresses the landing speed $V$ (in feet per second) as a function of the gross weight (in pounds) of the Piper Cheyenne aircraft. Find the inverse function. Use the inverse function to find the gross weight for a Piper Cheyenne for which the proper landing speed is $115 \mathrm{ft} / \mathrm{sec}$.
