    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.
