An **input-output table** is a two-column table in which the same rule is

applied to each input value resulting in the corresponding output values.

First, determine which operation to use.

Each cupcake can be thought of as a group of 7.

To solve for 6, 8, and 12 groups of 7, use multiplication.

The middle column is added temporarily to show the rule being applied.

Number of Cupcakes | multiply by number of candies per cupcake | Total Number of Candy Pieces |

6 | 6 × 7 | 42 |

8 | 8 × 7 | 56 |

12 | 12 × 7 | 84 |
