Question

A piece of paper measures 8.5 inches by 11 inches. Mrs. Wickowitz wants to hang paper on a bulletin board that has a height of 24 inches and an area of 1,728 square inches. Which inequality best represents the possible whole numbers of papers, p, that Mrs. Wickowitz could hang?

Answer 1

p <= 19

Explanation:

We have that the area of a sheet of paper is:

8.5 ft * 11 ft = 93.5 ft ^ 2

So the area of the bulletin board would come from:

1728 / 93.5 = 18.48 pieces of paper.

What it means is that the solution is a number greater than 18.48, an inequality this case represents would be:

p <= 19

Which means, as long as it's under 19, I could hang it up. It is approaching 19 because this type of situation approaches the largest number.
