Joanna takes a security interest in the equipment in Jason Store and files a financing statement claiming “equipment and all after-acquired equipment.” Berkeley later sells Jason Store a cash register, taking a security interest in the register, and (a) files nine days after Jason receives the register or (b) files twenty-five days after Jason receives the register. If Jason fails to pay both Joanna and Berkeley and they foreclose their security interests, who has priority on the cash register? Explain.
