Grace Co can further process Product B to produce Product C Product B is currently selling for $60 per pound and costs $38 per pound to produce Product C would sell for $95 per pound and would require

The differential revenue of producing and selling Product C is the difference between the revenue of selling Product C and the cost of producing it, compared to the revenue and cost of selling Product B.

For Product B: Revenue = $60 per pound Cost = $38 per pound

For Product C: Revenue = $95 per pound Cost = $38 per pound (from producing Product B) + $13 per pound (additional cost for processing) = $51 per pound

Therefore, the differential revenue of producing and selling Product C is:

$95 per pound (revenue from Product C) - $60 per pound (revenue from Product B) - $13 per pound (additional cost for processing) = $22 per pound

So the answer is not listed, but the correct differential revenue is $22 per pound
