Activity Cost Pool	Activity Rate
Supporting direct labor	$16	per direct labor-hour
Order processing	$202	per order
Custom designing processing	$254	per custom design

	Standard Model	Custom Design

Number of orders	2	3
Number of custom designs	0	3

Using the company's activity-based costing system, compute the customer margin of Big Sky Outfitters.(Negative amount should be indicated by a minus sign. Omit the "$" sign in your response.)

I'd love any help. I thought I did it correctly and came up with $1518 and it wasnt right, retried and came up with $7998 and still wasn't correct! I'd love to see what im doing wrong.
