Need help with all 3 parts of this question.

Airzone makes amateur drones, and it has two US based divisions. Division A makes drone kit. Division B assembles and configures drone. A new model of drone has been developed of which Airzone will sell for $540 each. Airzone is planning to let Division B to produce 1,200 units of fully assembled drone using its idle capacity. Division B purchases the drone kit from Division A. The company has a policy that internal transfers are priced at their fully allocated costs. Assume that the variable cost and allocated fixed cost for each set of drone kit at Division A are $195 and $88, respectively. Also assume that the assembling and administrative variable costs for each unit of drone at Division B are $185 and $75 (both are variable costs), respectively. (1) Assume that Division A has idle capacity of producing the 1,200 sets of drone kit for Division B. Should Division B purchase the drone kit from Division A and produce the fully assembled drones? Would the company as a whole benefits if Division B decides to purchase from Division A (hint: the fixed cost in Division A is unavoidable)? (2) Assume that the allocated fixed cost for each unit of drone at Division B is $75. The 1,200 units of drone are produced using the drone kits from Division A for the company's EU sales division, which sells the drones for $650 each. Suppose the EU and US governments allow either the variable or fully allocated cost to be used as a transfer price. The US income tax is 30%, the EU income tax is 55%, and the import duty to EU is 15%. Which price should Airzone use to minimize the total of income taxes and import duties? Compute the saving from your choice of transfer price versus the other. (3) If EU has passed a new law decreasing the income tax rate to 40% and increasing the import duty to 20%, what would be the choice of transfer price in (2)?
