Based on the above, information, what is Tom Division's lowest acceptable transfer price? b Based on the above, information, what is Jerry Division's highest acceptable transfer price? c. Assume Tom Division offers to sell 30,000 units to Jerry Division for $11.80 per unit and that Jerry Division refuses this price and will purchase from the outside supplier.
