    buying and reselling pineapples, quantity changing

    Antonio purchased 25 pineapples to sell in his shop.
    He offered each of them for sale at $1.20 more than he paid for them.
    However, 5 of the pineapples went bad and could not be sold.
    Overall, his total profit was $10.
    What price did he originally pay for each of the pineapples?

    p = purchase price per pineapple

    20(p + 1.20) - 25p = 10
