Please help me with the questions below

Cosgrove Company manufactures two products, Product K-7 and Product L-15. Product L-15 is of fairly recent origin, having been developed as an attempt to enter a market closely related to that of Product K-7. Product L-15 is the more complex of the two products, requiring 2 hours of direct labor time per unit to manufacture compared to 1 hour of direct labor time for Product K-7. Product L-15 is produced on an automated production line.
Overhead currently is applied to the products on the basis of direct labor-hours. The company estimated it would incur $659,973 in manufacturing overhead costs and produce 14,600 units of Product L-15 and 58,400 units of Product K- 7 during the current year.

Unit costs for materials and labor are:

	Product K-7		Product L-15
Direct material	$	12	$	29
Direct labor	$	7	$	20

Required:

a-1	Compute the predetermined overhead rate under the current method. (Do not round intermediate calculations. Round your answer to 2 decimal places. Omit the "$" sign in your response.)

a-2	Determine the unit product cost of each product for the current year. (Do not round intermediate calculations. Round your answers to 2 decimal places. Omit the "$" sign in your response.)

	Unit Product Cost
Product K-7	$
Product L-15	$

b.	The company is considering the use of activity-based costing as an alternative to its traditional costing method for manufacturing overhead. Data relating to the company's activity cost pools for the current year are given below:

	Total Cost		Product K-7	Product L-15	Total
Machine setups required	$	255,000	900	1,650	2,550
Purchase orders issued		54,677	565	184	749
Machine-hours required		163,620	7,410	10,770	18,180
Maintenance requests issued		186,676	721	861	1,582
	$	659,973

Using the data above, determine the unit product cost of each product for the current year. (Do not round intermediate calculations. Round your answers to 2 decimal places. Omit the "$" sign in your response.)
