Answer:

15

Step-by-step explanation:

Take x as how many pounds you need for the 6000 square feet

7 pounds                                x pounds

---------------                           -----------------------

2800 square feet                    6000 square feet

7*6000=42000

42000/2800=15

or you could find how many pounds you would need for 1 square feet.

7 pounds                              .0025 ponds

----------------                        -----------------------

2800 square feet               1 square feet

and then you could just multiply .0025 and 6000

so [tex].0025 * 6000[/tex] = 15
