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%
