|10.) Write the system of inequalities that is graphed|Cale is throwing a party. One package of wings costs |Andrew only has $14 for lunch. He wants to have at |

|here. |$7 (independent variable). Hot dogs cost $4 per |least one sandwich and one drink. If the deli sells |

| |pound. His budget must remain under $40, and Cale |sandwiches for $5 and drinks for $2, what combination |

|[pic] |knows he’ll buy at least 5 pounds of hot dogs. |could Andrew have for lunch? |

| | | |

| |12.) Cale writes the system of inequalities that |15.) Come up with some or all of the possibilities |

| |represents his food situation (because that’s the kind|for Andrew |

| |of stuff Cale does). What is it? | |

| | | |

| | | |

| | | |

|11.) EOCT practice: Write the system of | | |

|inequalities that is graphed here. | | |

|[pic] | | |

| | |16.) Let the number of sandwiches be the independent |

|y > -x + 1 and y > x – 5 | |variable. Write the system of inequalities for this |

|y > x + 1 and y > x – 5 | |situation. (hint: there are 3 inequalities) |

|y > -x + 1 and y > -x – 5 | | |

|D.) y > x + 1 and y > -x – 5 | | |

| |13.) Based on this graph, what are two examples of | |

| |purchases he can make? | |
