Answer :
Answer: a. Option A is correct. The sales price under GAAP would be $120,000, which is 20% more than the cost to produce the boat ($50,000 + $30,000 + $20,000 = $100,000, 20% of which is $20,000).
The sales price for internal decision purposes would be $136,800, which is calculated by adding the upstream and downstream costs to the cost to produce the boat, then multiplying by 1.2 ($5,000,000 + $2,000,000 + $100,000 = $7,100,000; 1.2 x $7,100,000 = $136,800).
Upstream works include the exploration and production of crude oil and natural gas, whilst downstream refers to the processes applied after extraction through to it being delivered to the customer in whatever format required.
