19 | 301 |

19 | 320 |

19.2 | 305 |

- Determine if the above relation (A, S) defines a function or not.
- Using Excel, draw a scatter diagram of data. Click here for a video explanation on how to create a scatter plot and linear regression.
- Using Excel, find the line of the best fit the models.
- Add this line to the scatter diagram.
- Interpret the slope and y-intercept of this equation.
- Express this equation as a function S of A and find its domain.
- Predict the sales if the advertising expenditure is $25000.

**Requirements:**

- Paper must be written in 3

#### Option #2: Demand and Pricing

As a marketing manager, you wish to find a function that relates the demand D for men’s shirts, and P the price of one shirt. Based on the price history, the following data were collected.

Price of One Shirt (P) | Demand (D) |

21 | 50 |

22 | 50 |

23.3 | 48 |

23.3 | 47 |

25 | 46 |

26 | 45 |

28 | 42 |

- Determine if the above relation (P, D) defines a function or not?
- Using Excel, draw a scatter diagram of data. Click here for a video explanation on how to create a scatter plot and linear regression.
- Using Excel, find the line of the best fit the models.
- Add this line in the scatter diagram.
- Interpret the slope and y-intercept of this equation.
- Express this equation as a function D of P and find its domain.
- How many shirts will be demanded if the price is $30?
