3. The following ﬁgure shows a ﬁrm’s isoquant for producing 2,000 units of output

and four isocost curves. Labor and capital each cost $50 per unit. 500 Units of capital

the input price ratio, wfr. The total cost of producing 2,000 units of output

with input combination A is $ By moving from A to B, the ﬁrm (increases, decreases) labor usage and (increases, decreases)

capital usage. At point B the MRTS is (greater than, less than, equal to) the input price ratio, w/r. The movement from A to B

(increased, decreased) total cost by 311 At Point D the ﬁrm (minimizes, maximizes) the cost of producing 2,000 units of output. The MRTS is (greater than, less than, equal to) the input price ratio, w/r. The optimal input combination is units of labor and

units of capital. At this combination, the total cost of producing 2,000 units is is At point E, the MP per dollar spent on is less than the MP per dollar spent on . The total cost of producing 2,000 units of output with input combination E is $
