Explanation: Given

Products      Sales Revenue    Traditional      ABC

Product 540X 198,200        54,440         45,520

Product 137Y 158,700       49,090          39,290

Product 249S 83,190         11,290         30,010

a)  computing  operating income using the traditional costing system for each product.

1) Product 540X

Operating income =  Revenues - Operating cost

198,200 - 54,440= $143,760

2)) Product 137Y

Operating income =  Revenues - Operating cost

158,700 - 49,090= $109,610

3) Product 249S  

Operating income =  Revenues - Operating cost

83,190    - 11,290    = $71,900

b)  computing  operating income using the activity-based costing system for each product.

1) Product 540X

Operating income =  Revenues - Operating cost

198,200 - 45,520= $152,680

2)) Product 137Y

Operating income =  Revenues - Operating cost

158,700 - 39,290= $119,410

3) Product  249S

Operating income =  Revenues - Operating cost

83,190    - 30,010    = $53,180

c) Using the following formula, computing  the percentage difference in operating income for each of the product lines of Sunland

PProduct 540X ={Operating Income (ABC)-Operating Income traditional cost)]divided operating Income (traditional cost)

= ($152,680 -$143,760)/$143,760 X 100 =8,920/143760X 100= 6.20%

Product 137Y  ={Operating Income (ABC)-Operating Income traditional cost)]divided operating Income (traditional cost)

= ( $119,410 -$109,610)/$109,610 X 100 =9800/109610 X100= 8.94%

Product  249S  ={Operating Income (ABC)-Operating Income traditional cost)]divided operating Income (traditional cost)

= (  $53,180-$71,900)/$71,900 X 100 =-18,720/71900X 100

= -26.04%

the answer should be demonstrations i hope this
