Answer:
$40
Step-by-step explanation:
Stand alone price of product A = $50
Stand alone price of product B = $100
Price of the combined product = $120
Now,
The allocation ration for the product A and B =
or
The allocation ration , product A : B =
or
The allocation ration, product A : B = 5 : 10
therefore,
Allocated to the performance obligation for delivering product A
= $120 ×

or
Allocated to the performance obligation for delivering product A
= $120 ×

or
= $40
Hence, the correct answer is option $40
