Here are some missing parts of your question.
contract price for a = 125,000, for b = 80,000
cost of related goods for a = 70,000 for b = 55,000
Explanation:
1. Both contracts should be combined for the the purpose of applying this model. so the answer is yes
2.
120000 + (5000 x 60%)
= 120000 + 3000
= $123000
80000 (5000 x 40%)
= 80000 + 2000
= $82000
from the question we were told that prices for Contract A is $120,000 while prices for Contract B is $80,000. the Contract price of Contract A put to be $125,000. so we have $5,000 more that should be shared between the contracts a and b. so the obligations for goods from A is calculated to be $123,000 and tht of contract B is $82,000.
c.
when control of goods is shifted to customer then the revenue has to be recognized
