Question

An economy is employing 2 units of capital, 5 units of raw materials, and 8 units of labor to produce its total output of 640 units. Each unit of capital costs $10; each unit of raw materials, $4; and each unit of labor, $3.
If the per unit price of raw materials rises from $4 to $8 and all else remains constant, the per unit cost of production will rise by about:

A) 50 percent.
B) 30 percent.
C) 40 percent.
D) 100 percent.

Answer 1

Answer:

B 30 percent

Explanation:

Initial cost of production = (2×$10) + (5×$4) + (8×$3) = $20+$20+$24 = $64

New cost of production = (2×$10) + (5×$8) + (8×$3) = $20+$40+$24 = $84

% rise in cost of production = (new cost - initial cost)/initial cost × 100 = (84 - 64)/64 ×100 = 20/64 × 100 = about 30%
