Answer:
In other words, if Neha decides to keep the $300 for a cell phone and Teresa decides to contribute the $300 to the public project, then Neha would receive a total benefit of:
$570.
Explanation:
Neha has, in this situation, maximized his benefits to the detriment of the public good. This is an illustration of the tragedy of the commons. The tragedy of the common is an economic problem that explains the loss that the society incurs when some persons like Neha neglect to contribute to the common good because they are solely concentrated on pursuing their individual goals for personal gains.
Answer: The correct answer is (A) : Positive upward slope.
Explanation: A demand curve is basically a graph like any other with the variables in potted on both the x-axis (left to right) and the y-axis (top to bottom). Understanding the definition of demand would make it easier to understand why the answer is option A and why the demand curve has a negative downward slope.
Demand can be defined as the quantity of a commodity or service that a consumer is willing and able to buy at a given price and at a particular point in time. And the law of demand states that “other factors being held constant, the higher the price of a commodity, the lower the quantity being demanded by the consumer. And the lower the price of a commodity, the higher the quantity being demanded by a consumer.”
This is simply a rational consumer behavior. So if the price of movie tickets were to go up let’s say from $10 to $15 then a consumer who previously could afford to watch 8 movies in a month (that’s $80) would be having second thoughts and so, rather than spend $120 per month on movie tickets, would be more inclined to watch less movies and stay within his/her $80 budget.
Therefore, on the demand curve, as the price of movie tickets moves positively towards the right side (on the x-axis), the quantity demanded would move negatively downwards (on the y-axis). As one variable increases the other one decreases, and vice versa. That explains why the demand curve has a negative downward slope.
Answer:
$1,213,657.685
Explanation:
For computation of compounded future value first we need to find out the present worth which is shown below:-


= $88,172.32636
Now, Future value = Present worth × (1 + interest rate)^number of years
= $88,172.32636 × (1 + 6%)^45
= $1,213,657.685
Therefore we have applied the above formula to determine the future value.
Answer:
Private saving = $3 trillion
National Saving = $2 trillion
Explanation:
Private saving = GDP - Taxes - Consumption + Transfer payments
Private saving = $18 trillion - $2 trillion - $13 trillion + 0
Private saving = $3 trillion
Government runs a deficit of $1 trillion means its spending is $1 trillion more than the tax revenue.
So, National Saving = Private saving + Public saving
National Saving = $3 trillion + ($2 trillion - $3 trillion)
National Saving = $3 trillion + (-$1 trillion)
National Saving = $2 trillion
