256 nails for $9.75. Therefore 512 nails $$= 2 * 9.75 = 19.50$$ 128 nails for$7.75. Therefore 512 nails $$= 4 * 7.75 = 31$$

Difference in the price $$= 31 - 19.50 = 11.50$$

Difference of $11.50 for 512 nails. Difference of Cost of one nail $$= \frac{11.50}{512} = 0.02$$. Answer (A)...

4 containers of 128 nails each cost 4 x 7.75, so per nail the cost is:

(4 x 7.75)/512 = 7.75/128 ≈ 0.06

2 containers of 256 nails each cost 2 x 9.75, so per nail the cost is:

(2 x 9.75)/512= 9.75/256 ≈ 0.04

Thus, each nail would cost approximately $0.02 more when the employee bought the nails in smaller containers instead of the larger containers.
