    (B) the total profit made by a person buys an item for 2.25 dollars and then sells the item for 2.25 dollars

    Step-by-step explanation:

    Let's analyse this using profit and loss formulas.

    Profit = Cost price - selling price

    In this case,:

    Cost price = $2.25

    Selling price is $2.25

    Profit = ?

    Let's invoke the formula:

    Profit = Cost price - selling price

    Profit = $2.25 - $2.25

    Profit = $0

    Therefore, the answer is (B)

    The total profit made by a person buys an item for 2.25 dollars and then sells the item for 2.25 dollars

    The answer is B

    Step-by-step explanation:

    When he bought the item he lost 2.25 dollars giving him a net profit of - 2.25

    When he sold it for 2.25 he gained a net profit of 2.25 which cancels out his negative net profit giving a final product of 0.
