Cannot finish my homework without these 3 problems but im really stuck, please help..

1. Rebelo Corporation is presently making part E07 that is used in one of its products. A total of 17,000 units of this part are produced and used every year. The company's Accounting Department reports the following costs of producing the part at this level of activity:

	Per Unit
Direct materials	$	3.80
Direct labor	$	3.80
Variable manufacturing overhead	$	1.10
Supervisor's salary	$	2.50
Depreciation of special equipment	$	1.40
Allocated general overhead	$	8.60

An outside supplier has offered to make and sell the part to the company for $20.80 each. If this offer is accepted, the supervisor's salary and all of the variable costs, including direct labor, can be avoided. The special equipment used to make the part was purchased many years ago and has no salvage value or other use. The allocated general overhead represents fixed costs of the entire company, none of which would be avoided if the part were purchased instead of produced internally. If management decides to buy part E07 from the outside supplier rather than to continue making the part, what would be the annual impact on the company's overall net operating income?

2. Drew Cane Products, Inc., processes sugar cane in batches. The company buys a batch of sugar cane from farmers for $90 which is then crushed in the company's plant at a cost of $11. Two intermediate products, cane fiber and cane juice, emerge from the crushing process. The cane fiber can be sold as is for $21 or processed further for $13 to make the end product industrial fiber that is sold for $45. The cane juice can be sold as is for $41 or processed further for $29 to make the end product molasses that is sold for $103. What is the financial advantage (disadvantage) for the company from processing one batch of sugar cane into the end products industrial fiber and molasses rather than not processing that batch at all?

3. Product U23N has been considered a drag on profits at Jinkerson Corporation for some time and management is considering discontinuing the product altogether. Data from the companys budget for the upcoming year appear below:

Sales	$	730,000
Variable expenses	$	350,000
Fixed manufacturing expenses	$	234,000
Fixed selling and administrative expenses	$	161,000

In the company's accounting system all fixed expenses of the company are fully allocated to products. Further investigation has revealed that $144,000 of the fixed manufacturing expenses and $93,000 of the fixed selling and administrative expenses are avoidable if product U23N is discontinued. The financial advantage (disadvantage) for the company of eliminating this product for the upcoming year would be:
