Q: Which of the following best describes the slope of the isocost line?

$$-\frac{\text{Price of Input 1}}{\text{Price of Input 2}}$$

Question 1

What does an isocost line represent in microeconomics?

Accepted Answer

All combinations of two inputs that can be purchased for a given total cost

Question 2

If a firm’s budget increases, what happens to its isocost line?

Accepted Answer

The isocost line shifts outward, parallel to the original

Question 3

Given the formula for the maximum quantity of an input: $$ 	ext{Max Quantity of Input} = \frac{	ext{Budget}}{	ext{Price of Input}} $$, what is the maximum number of ovens a bakery can buy if its budget is $$\2400$ and each oven costs $$\$$600$$?

Accepted Answer

$$4$$ ovens

Question 4

Suppose the price of bakers increases while the price of ovens and the budget remain constant. What happens to the isocost line?

Accepted Answer

The isocost line becomes steeper

Question 5

If a bakery spends all its budget on bakers, which point does it reach on the isocost line?

Accepted Answer

The horizontal intercept

Question 6

Which of the following best describes the slope of the isocost line?

Accepted Answer

$$-\frac{	ext{Price of Input 1}}{	ext{Price of Input 2}}$$

Question 7

A bakery can hire bakers at $$\1$$,200$$ each and buy ovens at $$\$$600$$ each with a budget of $$\2$$,400$. If it spends all its money on ovens, how many can it buy?

Accepted Answer

$$4$$ ovens

Question 8

If the price of ovens decreases while the budget and price of bakers remain constant, what happens to the isocost line?

Accepted Answer

The isocost line becomes flatter

Question 9

Which of the following equations correctly represents the isocost line for two inputs, $$x$$ and $$y$$, with prices $$P_x$$ and $$P_y$$ and budget $$C$$?

Accepted Answer

$$P_x x + P_y y = C$$

Question 10

A bakery faces a budget of $$\2$$,400$$, with ovens costing $$\$$600$$ each and bakers costing $$\1$$,200$ each. If it buys 2 ovens, how many bakers can it hire with the remaining budget?

Accepted Answer

1 baker

Question 11

If the price of one input increases, what happens to the intercept of the isocost line on the axis representing that input?

Accepted Answer

The intercept moves closer to the origin

Question 12

Which of the following changes will NOT affect the slope of the isocost line?

Accepted Answer

An increase in the budget

Question 13

If a bakery’s budget doubles and the prices of inputs remain constant, what happens to the isocost line?

Accepted Answer

It shifts outward, parallel to the original

Question 14

Suppose a bakery can hire bakers at $$\1$$,200$$ each and buy ovens at $$\$$600$$ each. If it spends $$\1$$,800$ on 1 baker and the rest on ovens, how many ovens can it buy?

Accepted Answer

2 ovens

Question 15

Which of the following best describes the effect of an increase in the price of bakers on the isocost line?

Accepted Answer

The isocost line becomes steeper
