# Isoquant and isocost curves

The following production table provides estimates of the maximum amounts of output possible with different combinations of two input factors, X and Y. (Assume these are just illustrative points on a spectrum of continuous input combinations.)

Units of Y

Used Estimated Output per Day

5 184 265 334 395 440

4 176 248 303 352 395

3 164 216 264 303 334

2 128 176 216 248 265

1 88 128 164 176 184

1 2 3 4 5

Units of X Used

a. List the different combinations of inputs X and Y that, if graphed, would illustrate an isoquant for an output of 176.

b. Assuming that output sells for $3 per unit and X is fixed at 4 units, complete the following table:

Units of Y employed Total Product (Output) Marginal Product (Output) Value Marginal Product of Y

1 176 176

2

3 55

4 49 147

5 395 129

c. Assuming still that X is fixed at 4 units, the output of the production process sells for $3, and the cost of Y is $135 per day, how many units of Y will be employed? Explain how you reached your answer.

d. Suppose that the cost of units of both input X and input Y are the same at $135 per day. Describe how isocost curves for a cost of $135 and also for a cost of $270 would look. How would you describe both the shape and slope of the isocost curves?
