Question

This is dimensional analysis!!

Answer 1

Before we answer the question we must first:1. Assess what we have so far.2. Know what we need to find.3. Solve.4. Conclude.
Step 1: What we have so far.*Price of a ream of paper = $4.00
*No. of sheets of paper in a ream = 500pcs.
*A sheet of paper weighs = 0.50oz
Step 2: What we need to find.*The price of 1lb (pound) of paper = ?
Step 3: Solve.*1lb = 16oz
Know how many papers are there in 1lb:
*1lb = 16oz
*1 sheet of paper = 0.50oz
*16oz of paper = 32 pcs of paper.
Because 16 divided by 0.50 is = 32.
*1lb of paper =  32 pcs of paper.

Know how the weight of a ream of paper:
*Ream of paper has 500 papers.
*32 papers = 1lb
500 divided by 32 = 15.625
*Weight of a ream is 15.625lb.

Know how much a pound (lb) of paper is:
*A ream of paper costs $4.00.
*A ream of paper weighs 15.625lb.
4.00 divided by 15.625 = 0.256
*Cost per pound (lb) of paper = $0.256 or $0.26 or 26 cents.

Step 4: Conclusion.After successfully doing the steps above, we can now conclude that the cost per pound of paper is $0.256 or $0.26 or 26 cents.
