Explanation:
The preparation is shown below:
Particulars	Product X	Product Y	Product Z
Units produced 1,600           2,100         3,100
Sales Value at split off per unit	$14	$19	$16
Total Sales Value at split off   (a)	$22,400	$39,900	$49,600
Units produced	1,600	2,100	3,100    (X)
Sales Value per unit	$20	$20	$25
Additional Processing cost per unit	$5	$7	$7
Net Realizable Value = Sales value - Further costs	$15	$13	$18
 (y) 
Total Realizable Value if processed further (b) $24,000	$27,300	$55,800   (x × Y)
Difference = b- a $1,600	-$12,600          $6,200

As the product X and product Z contains positive number so it should be processed and Product Y should not be processed as it contains negative number
