(a)
The price on the vertical axis and quantity on the horizontal axis and to plot the first two columns.
Answer to Problem 1E
Hence, the price along the vertical axis and the quantity along the horizontal axis has been determined and the first two columns have been plotted.
Explanation of Solution
The graph is plotted by joining 3 points of price on Y-axis to the corresponding quantity sold on the X-axis.
To find the quantity sold when the price is a certain dollar, we can take the help of the line obtained by plotting 3 price point in the Y-axis to the corresponding quantity in the x-axis in the graph sheet, and join them to form a sloping straight line.
Once the new quantity is found for a particular price point from the above straight line, we can use this information to find the total revenue at that price.
(b)
The quantity sold when the price is $550.
Answer to Problem 1E
When the price is 550$, the quantity sold is 1100.
Explanation of Solution
From the above-plotted line on the graph, we find that the point when the price on Y-axis is 550$, the corresponding quantity sold on X-axis is 1100 numbers.
To find the quantity sold when the price is a certain dollar, we can take the help of the line obtained by plotting 3 price point in the Y-axis to the corresponding quantity in the x-axis in the graph sheet, and join them to form a sloping straight line.
Once the new quantity is found for a particular price point from the above straight line, we can use this information to find the total revenue at that price.
(c)
To plot a graph and to measure the quantity on the horizontal axis and to determine the total revenue on the vertical axis.
Answer to Problem 1E
The graph is plotted and the quantity sold at 550$ is 1100 numbers.
Explanation of Solution
Now in the graph drawn above, the quantity sold is taken on X-axis while the total revenue obtained for that numbers of corresponding quantity sold is taken on Y-AXIS.
Next, we plot the points of total quantity sold on the horizontal X-axis versus the total Revenue obtained by selling each number of that quantity on the vertical Y-Axis. We take such thee points where the quantity-sold and corresponding revenue interacts, and join them to form a straight line.
To find the quantity sold when the price is at a certain dollar, we can take the help of the line obtained by plotting 3 price point in the Y-axis to the corresponding quantity in the x-axis in the graph sheet, and join them to form a sloping straight line.
Once the new quantity is found for a particular price point from the above straight line, we can use this information to find the total revenue at that price.
(d)
The total revenue when the price is $550 and to determine if the total revenue will increase or decrease when the price is lowered.
Answer to Problem 1E
When the quantity sold is $ 550, the total revenue is $ 6,40,000.
Explanation of Solution
We already know the quantity sold at each price point. Conversely, we know the price too when a particular number of items is sold. In this problem, the total revenue is to be found when the price is 550$. Now the corresponding total revenue to 1100 numbers is found to be 6,40,000 on the Y-axis. As we can see from the graph, decrease in price will increase the revenue.
To find the quantity sold when the price is a certain dollar, we can take the help of the line obtained by plotting 3 price point in the Y-axis to the corresponding quantity in the x-axis in the graph sheet, and join them to form a sloping straight line.

We assume that c{(e) 0 for i = 1,2 and for any level of emission e we have c₁'(e) # c₂' (e). Furthermore, assume the two firms make different contributions towards pollution concentration in a nearby river captured by the transfer coefficients ε₁ and 2 such that for any level of emission e we have C₂'(e) # The regulator does not know the resulting C₁'(e) Τι environmental damages. Using an analytical approach explain carefully how the regulator may limit the concentration of pollution using (i) a Pigouvian tax scheme and (ii) uniform emissions standards.

Then they jump to $750 per year, with an annual increase of $500 per year.Bill’s dad wants to keep his annual cost of car ownership low.

- A mining corporation purchased $120,000 of production machinery and depreciated it using 40% bonus depreciation with the balance using 5-year MACRS depreciation, a 5-year depreciable life, and zero salvage value. The corporation is a profitable one that has a 22% combined incremental tax rate. At the end of 5 years the mining company changed its method of operation and sold the production machinery for $40,000. During the 5 years the machinery was used, it reduced mine operation costs by $32,000 a year before taxes.
