    Belle bought 30 pencils for $1560. She made a profit of $180. How much profit did she make on each pencil

    The cost per pencil is:
    1560/30 = 52

    Build revenue function:
    Revenue = Number of Pencils * Sales Price (s)
    Revenue = 30s

    The profit equation is:
    Profit = Revenue - Cost

    Given profit is 180 and cost is 1560, we have:
    30s - 1560 = 180

    To solve for s, we type this equation into our search engine and we get:
    s = 58

    This is sales for total profit. The question asks profit per pencil.
    Profit per pencil = Revenue per pencil - Cost per pencil
    Profit per pencil = 58 - 52
    Profit per pencil = 6
