Answer:
D. The marginal cost of light is zero, and by convention zero-priced goods and services are excluded from GDP
Explanation:
Only things that have a monetary cost are included in GDP. Things that do not cost "anything" in monetary terms are not included, and this is a major shortcoming of GDP.
From an ecological economics standpoint, things like sunlight, air, and water are often not valued and included in GDP. This is the same case as in the question, because the marginal cost of light is zero, then, it is not included in GDP.
Answer: $750,000
Explanation:
Given that,
Fixed price contract = $10,000,000
Cost incurred in the first year = $3,000,000
Remaining costs to complete = $5,000,000
Tullis billed = $4,000,000 in year 1
Collected by the end of the year = $3,500,000
Percentage of work completed = 
= 
= 37.5%
Revenue recognized = 37.5% of $10,000,000
= $3,750,000
Income recognized = Revenue recognized - Cost incurred in the first year
= $3,750,000 - $3,000,000
= $750,000
Answer:
The law of demand states that consumers will request more of a product if its price decreases. For supplement goods, an increase in the price of one will increase demand for the other. The demand curve for apples will react as follows.
Explanation:
<u>A). More people begin to prefer apples to oranges.</u>
Should peoples' preference change to apples, the demand for oranges will decrease while that of apples will increase. The demand curve is downward sloping. If demand increases, the demand curve will shift to the right. It is also referred to as moving outwards. In this case, the demand curve for apples will shift to the right.
B) <u>The price of peaches rises (because peaches are a substitute for apples).</u>
Substitutes imply a good can be used in place of another. If the price of a substitute increases, it demands decreases. The demand for the substitute good will go up. An increase in the price of peaches will increase the demand for apples. As a result, the demand curve will shift outwards. In other words, shift to the right.
C. People's incomes rise (and apples are a normal good).
Demand for normal goods increase as the people's income rises. More people will afford to buy apples. If people are now earning more, the demand for apples will go up. The demand curve will shift to the right to indicate a surge in demand.
