Two firms, a and b, compete in a market to sell homogeneous products with inverse demand function P = 400 – 2Q where Q = Q_a + Q_b. Firm a has the cost function C_a = 100 + 15Q_a and firm b has the cost function C_b = 100 + 15Q_b. Use this information to compare the output levels, price and profits in settings characterized by the following markets:

Finish the C++ program below based on

(0 <= F < 60, 60 <= D < 70, 70 <= C< 80, 80 <= B < 90, 90 <= A <= 100)

THE RULES: · You need to have a total grade >=90 and average in projects >= 90 to get an A; · You need to have a total grade >=80 and < 90, and average in projects >=80 to get a B; · You need to have a total grade is >=70 and < 80, and average in projects >=70 to get a C. Poor attendance will be penalized by up to 10% of the final total grade. The grades of all the students and attendance

penalty are stored in an external file called grade120.dat. which will be given

Question 19 (3 points)

Frank's Fish Fry sells fish fry dinners. Frank's revenue equals the quantity of fish fry dinners he sells times the price he charges for a fish fry dinner.

From last year to this year, his quantity increases by 4% and the price he charges increases by 3%. Frank's revenue increases approximately by

UR Safe Systems installs home security systems. Two of its systems, the ICU 100 and the ICU 900, have these characteristics:

Design SpecificationsICU 100ICU 900Cost DataVideo cameras 3  1 $105/eaVideo monitors 3  3 $45/eaMotion detectors 3  6 $10/eaFloodlights 1  5 $4/eaAlarms 3  2 $10/eaWiring 680ft. 1,080ft.$0.1/ft.Installation 14hr 24hr$10/hr

The ICU 100 sells for $830 installed, and the ICU 900 sells for $1,540 installed.

Required:

1. What are the current profit margin percentages on both systems?

2. UR Safe’s management believes that it must drop the price on the ICU 100 to $770 and on the ICU 900 to $1,410 to remain competitive in the market. Recalculate profit margin percentages for both products at these price levels and then compute the target cost needed for each product to maintain the current profit margin percentages.

(For all requirements, round your percentage answers to 2 decimal places and other answers to the nearest whole dollar amount.)

Beatriz enjoys writing and uses a large amount of paper. Currently, paper costs $2.00 for 100 sheets. The formula for her demand curve is S=525−50PS, where PS is the price of 100 sheets and S is the number of packages of 100 sheets. The governor of her state has proposed taxing paper at the rate of $1.50 for each 100 sheets. Assume this policy would increase the price of paper to $3.50 (including tax). Draw Beatriz's demand curve. Instructions: Use the tool provided "Demand" to plot Beatriz's demand curve. The x-axis represents S, and the y-axis represents PS. a. Compute the change in her consumer surplus for the proposed tax increase. Instructions: Round your answer to 2 decimal places. Include a negative sign if necessary. $ b. How much revenue will the government raise by taxing Beatriz? Instructions: Enter your answer as a whole number. $ What is the combined change in government revenue and consumer surplus? Instructions: Enter your answer as a whole number. Include a negative sign if necessary. $ Does the new tax raise enough revenue for the government to compensate Beatriz for her loss? Yes No

A person has $250 to spend on two goods (x and y) whose respective prices are $2 per unit and $5 per unit.

1. Draw the budget line showing all the different combinations of the two goods that can be bought with the given budget.
2. What happens to the budget line if the budget (money available to spend) increases by 100%.
3. What happens to the budget line if the price of good x decreases by 50%?
4. What happens to the budget line if the price of good y increases to $10 per unit?

3. [National Income Model] 30 points

Let

AE =C+I+G+NX

where AE is the aggregate expenditure, C is the consumption function, I is investment,

G is government expenditure and NX is the net export. Given

C =100+0.65Y

where Y is the national income and

1. =100, G=100+0.10Y, NX =0

1. Graph the consumption function withY on the horizontal axis andC on the vertical axis.
2. Graph the aggregate expenditure function with Y on the horizontal axis and AE on the vertical axis.
3. Find the equilibrium level of income without using graph analytically.
4. Find the equilibrium level of consumption C.

Monopoly pricing: Consider a simple linear demand function that intersects the quantity 0 point at $110 and the $0 axis at 1,200 units. The marginal cost is linear and starts at $10 at 0 quantity and reaches $110 at 500 units.

1. What is the elasticity of demand? Is it constant? Why or why not?
2. What is the competitive market clearing price?
3. What is the competitive consumer surplus?
4. What is the competitive producer profit (surplus)?
5. What is the profit-maximizing monopoly price and quantity?
6. At that price, what is the consumer surplus?
7. If we allow the producer to segment the market, so that it can pick 100 consumers that have to pay their willingness to pay (i.e., according to the demand function at quantity 100), how do consumer surplus and profit change?
8. If we assume a mind-reading producer who can price-differentiate so that each consumer pays according to their position on the demand curve, how do profit and consumer surplus change? (In other words, consumers are lined up according to the demand curve and get served at that price.)

It is probably easiest to use algebraic representations for the curves, rather than trying to do this graphically. Show your work.
