Use the table from question 1 to complete the next six questions. Enter the correct values in the boxes below. Enter only whole numbers (no commas, no decimals, no dollar signs). Each fill-in-the-blank below is worth 3 points.

This profit maximizing firm will hire [removed] workers.

3.

This profit maximizing firm will produce [removed] units of output.

4.

This firm’s maximum profit equals [removed] .

5.

Now suppose that the wage falls to $170. You will need to recalculate the values from the table, given this new wage, to answer the questions below.

This profit maximizing firm will now hire [removed] workers.

6.

This profit maximizing firm will now produce [removed] units of output.

7.

This firm’s maximum profit now equals [removed] .

8.

Use the following information to answer the next nine questions. Each fill-in-the-blank is worth 3 points.

If your answer is in decimal form, enter it with 2 decimal places. For example, if your answer is .4, enter it into the fill-in-the-blank as .40, or if your answer is 1.4, enter it into the fill-in-the-blank as 1.40. If there are no decimals in your answer, you will simply enter the number; so if your answer is 2, enter 2 with no decimals. Do not use commas.

Suppose the economy is characterized as follows:

AE = C + I + G + (X-M)

C = 800 + .75(Y – T) - 30 (r)

I = 600 – 50(r)

G = 300

X- M = -25

T = 80

r = 5

Price level P is fixed at 1 (P=1)

Use the information above to get expressions for the consumption function and the AE equation.

The vertical intercept for the consumption function is [removed] .

9.

The slope of the consumption function is [removed] .

10.

The vertical intercept of the AE equation is [removed] .

11.

Use the following information to answer the next four questions. Each multiple choice question is worth 3 points.

mm = money multiplier = .8
