Proportional Relationships Tasks – Part IV Daily Two 1.BeatStreet, TunesTown, and MusicMind are music companies. BeatStreet offers to buy 1.5 million shares of TunesTown for $561 million. At the same time, MusicMind offers to buy 1.5 million shares of TunesTown at $373 per share. Who would get the better deal, BeatStreet or MusicMind? What is the total price difference?

Proportional Relationships – Part IV Daily Two 1.BeatStreet, TunesTown, and MusicMind are music companies. BeatStreet and MusicMind are teaming up together to make an offer to acquire 1.5 million shares of TunesTown worth $374 per share. They will offer TunesTown 20 million shares of BeatStreet worth $25 per share. To make the swap even, they will offer another 2 million shares of MusicMind. What price per share (in dollars) must each of these additional shares be worth? 2.If a relationship has a unit rate, is it a proportional relationship? Explain.

Learning Targets #2: I can decide whether two quantities are in a proportional relationship. #3:I can represent proportional relationships by equations.

5
A text book has the following definition for two quantities to be directly proportional: We say that y is directly proportional to x if y=kx for some constant k. For homework, students were asked to restate the definition in their own words and to give an example for the concept. Below are some of their answers. Discuss each statement and example. Translate the statements and examples into equations to help you decide if they are correct.

6
Marcus: This means that both quantities are the same. When one increases the other increases by the same amount. An example of this would be the amount of air in a balloon and the volume of a balloon.

7
Sadie: Two quantities are proportional if one change is accompanied by a change in the other. For example the radius of a circle is proportional to the area.

8
Ben: When two quantities are directly proportional it means that if one quantity goes up by a certain percentage, the other quantity goes up by the same percentage as well. An example could be as gas prices go up in cost, food prices go up in cost.

9
Jessica: When two quantities are proportional, it means that as one quantity increases the other will also increase and the ratio of the quantities is the same for all values. An example could be the circumference of a circle and its diameter, the ratio of the values would equal π.
