3. In a closed economy, national savings equals investment
Explanation:
For a closed economy, the formula for calculating GDP = C + I + G
Where C - Consumption
I - investment
G - Government Spending
To find investment ,
750 = 300 + I + 400
I = $ 50 million
National savings = private saving + Government saving
Private saving = Y − T − C
750 - 300 - 250 = $200 million
Public savings = T - G
250 - 400 = $-150 million
National savings = $200 - $ 150 million = $ 50 million
Nb - All numerical values are in $ millions
The amounts for recording properties and services purchased by a business are determined using the cost concept.
<h3>Which principle determines the amount initially entered into the records for purchases?</h3>
A principle of accounting establishes the initial amount entered for purchases in the accounting records. According to the cost idea of accounting, all purchases of items (such as assets or items required for spending) should be recorded and kept in books at their original cost. Therefore, unless specifically indicated differently, it should be understood that an asset's value on a balance sheet represents its cost. Let's use the case of a company that pays cash or bank for a building worth $200,000. The worth of the building will be recorded in the accounting records using the cost concept of accounting, which equals $2,000,000. After four years, the building's worth increased to $1,000,000.

.

The z-score that yields a p-value of 0.3375 is -0.4193.
Thus, super discount airlines should overbook the flight by 35 + (-0.4193 x 24) = 35 - 10.0632 = 24.9368 = 25 seats.
Therefore, super discount airlines should overbook the flight by 25 seats.
