6-31.

Ms. Jancsi bought a new package of border decoration to put around the bulletin board in her classroom. The package contains $300$ inches of border. The dimensions of the rectangular bulletin board are $8$ feet by $3$ feet. If she puts the border around all four sides of the bulletin board, how much leftover bulletin material will she have? Include a labeled sketch in your answer.

Use the following sketch to help you find out how much leftover material Ms. Jancsi will have.

It may be useful to express all the lengths as inches.
$8$ feet is the same as $8$ groups of $12$ inches in each foot, or $8(12) = 96 \text{ inches}$.
Now, you can change the other side to inches and then find the perimeter of the bulletin board?
