This document provides instructions for Project 3 of a professional communication course. It asks students to complete a left brain/right brain exercise and write two paragraphs describing techniques they use to stay calm in difficult situations, referencing a chapter. It also provides instructions for Part 2 of a capstone project, which involves interviewing a customer service representative. Students are asked to identify potential interviewees, develop an introductory email, and submit their materials to an online folder.

1. CSS120 Professional Communication/Call Center: Project 3
Are You a Left Brain or Right Brain?
Project 3. Are You a Left Brain or Right Brain?
Complete the Left Brain, Right Brain exercise on page 216. Are
you a left brain or right brain? Do you agree or disagree with
your results? Why or Why not?
Staying calm when faced with a difficult situation requires that
you have good habits in place for dealing with pressure. Write
two paragraphs (3 to 5 sentences) describing what techniques
you use to calm yourself when facing a difficult situation.
Briefly describe the benefits you derive from these habits.
Reference chapter 5 page 203-209 in your response and include
what additional techniques you can incorporate in your habit.
Submit your writing to the Project 3 Dropbox folder on D2L.

calculate total cost and then, on graph paper, plot the total
fixed, total variable, and total cost schedules.

tell?

3. Suppose a firm’s technology is described by a production
function where the quantity produced is equal to the square root
of capital times labor (that is, Q = √(L●K)
a.
Using graph paper, draw the isoquant for three different levels
of output: 2, 4, and 6 units (hint: you will need to find different
combinations of L and K that will make Q equal these output
values. For example, both L=1, K=4 and L=2, K=2 make Q=2,
so both of these combinations of L and K are on the Q=2
isoquant.)
b.
Suppose the price of L and K is $3/hour. On your graph, show
isocost lines corresponding to total costs of $12, $24, and $36.
Using the isoquants and isocost lines, locate three points on the
expansion path and draw the expansion path.
c.
Does this production function exhibit increasing, decreasing, or
constant returns to scale?
d.
Using the three points you found on the expansion path,
4. calculate the firm’s long run total and average costs at each of
those points. Summarize your calculations in a table and in a
graph.
e.
Suppose amount of capital the firm uses in the short run is fixed
at 4 units. On your isoquant/isocost diagram illustrate the three
points corresponding to output levels of 2, 4, and 6. Calculate
the firm’s short run total and average costs and draw them in
the same graph with the long run costs.
f.
Why do the short run and long run average cost curves have
different shapes?
4. Suppose a firm’s technology is described by a production
function where the quantity produced is equal to the square root
of capital times labor (that is, Q = √(L●K)
a.
Using graph paper, draw the isoquant for output = 8 units.
b.
Suppose the firm has $128 to spend on its variable inputs and
the price of L and K is $8. On the same graph on which you
drew the isoquant, draw the isocost line. What is the optimal
combination of labor and capital?
c.
Suppose the price of labor increases to $16 and the price of
capital decreases to $4. draw the new isocost line and
determine the new optimal combination of labor and capital.
d.
Repeat c) for price of labor at $4 and capital at $16.

6. Suppose a firm can spend up to $1000 acquiring two variable
inputs, labor (L) and capital (K). The price of each unit of
labor is $25. The price of each unit of capital is $100.
a.
draw the firm’s isocost line.
b.
suppose the firm had $2000; draw the new isocost line.
c.
suppose the firm had $500; draw the new isocost line.
7. What is does the term “marginal rate of technical
substitution” refer to? Illustrate.

10. Suppose the wage rate is $25 per hour and the rent on
capital is $50 per hour. The equation for the isocost line is:
11. Suppose a firm is producing 2,475 units of output by hiring
50 workers (W = $20 per hour) and 25 units of capital (R = $10
9. per hour). The marginal product of labor and marginal product
of capital are 40 and 25, respectively. Is the firm minimizing
the cost of producing 2,475 units of output? If not, how should
the firm change its usage of L and K?
12. Suppose a firm's short-run production function is given by Q
= 16L0.8. What is the marginal product of the fourth worker?
13. Amazon’s fulfillment center in Salem can sort and pack
boxes. The boxes can be produced using only robots (K),
workers (L), or a combination of the two. K and L are perfect
substitutes for one another. Assume Amazon has TC = $100, K
costs $10/robot and L costs $20/workers. How much K & L will
Amazon use? Draw isoquants and an isocost line as part of your
answer.
14. On separate graphs, draw a SR total product curve, a SR
marginal product curve, a SR total cost curve, and a SR
marginal cost curve. On the graphs show what economic
concept they have in common.
15. What is the marginal-average rule?
16. The firm's long-run total cost is given by LTC = 100Q –
10Q2 + (1/3)Q3, and long-run marginal cost is given by LMC =
100 – 20Q + Q2. At what output level does the firm have
economies of scale?
17. Producing 200 units of good Y and 100 units of good X in
the same factory costs the firm $50,000. In contrast, producing
200 units of good Y in one factory and 100 units of good X in
another factory costs the firm $75,000. So if the firm produces
the two goods together, it achieves:
18. The total cost of producing 7 units of output is:

10. The firm's average total cost curve appears in which of the
following panels?
20. Suppose a firm's total cost is given by TC = 100 + 4Q +
2Q2. Write the expression or equation for TFC, TVC, ATC,
AFC, AVC, and MC.
