Check Your Understanding 12-1 Question 1 Bernie’s ice-making company produces ice cubes using a 10-ton machine and electricity. The quantity of output, measured in terms of pounds of ice, is given in this table:

3
1ai) Bernie’s ice-making company produces ice cubes using a 10-ton machine and electricity. The 10-ton machine is a _____ input. 1.fixed 2.variable

4
1aii) Bernie’s ice-making company produces ice cubes using a 10-ton machine and electricity. The electricity is a _____ input. 1.fixed 2.variable

5
1bi) Calculate the marginal product of the third unit of the variable input

6
1bii) The calculation of all of the marginal products reveals that there are _______ returns to the input. 1.increasing 2.diminishing

7
1ci) Bernie’s ice-making company produces ice cubes using a 10-ton machine and electricity. Suppose a 50% increase in the size of the fixed input increases output by 100% for any given amount of the variable input. What is the fixed input now? 1.the 10 ton machine 2.the 15 ton machine 3.the 20 ton machine 4.6 kilowatts of electricity

8
1cii) Suppose a 50% increase in the size of the fixed input increases output by 100% for any given amount of the variable input. Given the original production function, the quantity of ice that can be produced using 2 units of the variable input is _____

Check Your Understanding 12-2 Question 1 Alicia’s Apple Pies is a roadside business. Alicia must pay $9 in rent each day. In addition, it costs her $1.00 to produce the first pie of the day, and each subsequent pie costs 50% more to produce than the one before. For example, the second pie costs $1.00 × 1.5 = $1.50 to produce, and so on.

1ai) Alicia must pay $9 in rent each day. In addition, it costs her $1.00 to produce the first pie of the day, and each subsequent pie costs 50% more to produce than the one before. For example, the second pie costs $1.00 × 1.5 = $1.50 to produce, and so on. Calculate Alicia’s marginal cost of the 3rd pie. 1.$ $ $ $3.00

15
1aii) Calculate Alicia’s variable cost of producing 3 pies (Hint: The variable cost of two pies is just the marginal cost of the first, plus the marginal cost of the second pie, and so on.) 1.$ $ $ $4.75

16
1aiii) Alicia must pay $9 in rent each day. In addition, it costs her $1.00 to produce the first pie of the day, and each subsequent pie costs 50% more to produce than the one before. Calculate Alicia’s average fixed cost of producing 3 pies. 1.$ $ $ $3.00

1bi) The spreading effect dominates the range of output from _____. 1.0 to to to to

20
1bii) The diminishing returns effect dominates the range of output from _____. 1.0 to to to to

21
1ci) What is Alicia’s minimum cost output? 1.1 pie 2.2 pies 3.4 pies 4.5 pies

22
1cii) Making one more pie raises average total cost when output is greater than 4 pies because the marginal cost of the 5 th pie is less than the average total cost of the first four pies. 1.True 2.False

27
1aiv) Which choice leads to the lowest average total cost of producing 30,000 units? 1.Choice 1 2.Choice 2 3.Choice 3

28
1bi) Suppose that a firm has the choices 1, 2, and 3. Historically they have produced 12,000 units. Suddenly, demand increases sharply leading to a permanent change in production for the firm from 12,000 units to 22,000 units.
