Cell Phone Usage Use plurality with elimination to determine the preferred cellular phone service in Exercise 18.

To determine

Using the Borda count method, which provider is the favorite of these customers?

**Given Information:**

Rankings | ||||||

AT & T | â€ƒâ€ƒ | â€ƒâ€ƒ | â€ƒâ€ƒ | â€ƒâ€ƒ | â€ƒâ€ƒ | |

Sprint Nextel | â€ƒâ€ƒ | â€ƒâ€ƒ | â€ƒâ€ƒ | â€ƒâ€ƒ | â€ƒâ€ƒ | |

Verizon | â€ƒâ€ƒ | â€ƒâ€ƒ | â€ƒâ€ƒ | â€ƒâ€ƒ | â€ƒâ€ƒ | |

T-Mobile | â€ƒâ€ƒ | â€ƒâ€ƒ | â€ƒâ€ƒ | â€ƒâ€ƒ | â€ƒâ€ƒ | |

Number of Votes | â€ƒâ€ƒ | â€ƒâ€ƒ | â€ƒâ€ƒ | â€ƒâ€ƒ | â€ƒâ€ƒ |

**Concept used:**

Since a senior high school class held an election for class president, therefore which student is class president is selected by plurality elimination method, second choice becomes first, 3^{r}^{d} choice become 2^{n}^{d}, 4^{t}^{h} choice becomes 3^{r}^{d} ,

**Calculation:**

In the table AT & T never got 1^{s}^{t} position therefore it is eliminated as new preference shown in table below
