Can someone please help me with the following question?

Thermal Rising, Inc., makes paragliders for sale through specialty sporting goods stores. The company has a standard paraglider model, but also makes custom-designed paragliders. Management has designed an activity-based costing system with the following activity cost pools and activity rates:

Activity Cost Pool	Activity Rate
Supporting direct labor	$	16	per direct labor-hour
Order processing	$	190	per order
Custom design processing	$	251	per custom design
Customer service	$	424	per customer

Management would like an analysis of the profitability of a particular customer, Big Sky Outfitters, which has ordered the following products over the last 12 months:

	Standard Model		Custom Design
Number of gliders		14		3
Number of orders		1		3
Number of custom designs		0		3
Direct labor-hours per glider		29.50		32.00
Selling price per glider	$	1,600	$	2,370
Direct materials cost per glider	$	466	$	574

The companys direct labor rate is $20 per hour.

Required:

Using the companys activity-based costing system, compute the customer margin of Big Sky Outfitters. (Round your intermediate calculations and final answer to the nearest whole dollar amount. Loss amounts should be entered with a minus sign.)
