Hello, can you please check my answer for me. thank you very much.

Carmen Co. can further process Product J to produce Product D. Product J is currently selling for $23.10 per pound and costs $14.55 per pound to produce. Product D would sell for $36.80 per pound and would require an additional cost of $9.65 per pound to produce.

What is the differential cost of producing Product D?

a.$9.65 per pound

b.$11.58 per pound

c.$7.72 per pound

d.$5.79 per pound

Pound to produce so my answer is D 5.79 per pound.
