MC Qu. 74 Differential Chemical produced... Differential Chemical produced 12,000 gallons of Preon and 16,000 gallons of Preon. Joint costs incurred in producing the two products totaled $8,500. At the split-off point, Preon has a market value of $6.00 per gallon and Preon $3.00 per gallon. Compute the portion of the joint costs to be allocated to Preon if the value basis is used.

$5,100

Explanation:

The calculation of the portion of the joint cost for Preon allocation is shown below:

= Total joint cost for two products × (Preon cost ÷ Total cost)

Here,

Total joint cost = $8,500

Preon cost = 12,000 gallons × $6 per gallon = $72,000

And, the total cost is

= 12,000 gallons × $6 per gallon + 16,000 gallons × $3 per gallon

= $72,000 + $48,000

= $120,000

So, the allocated cost should be  

= $8,500 × ($72,000 ÷ $120,000)

= $5,100

= $4,500

ans.

heterothermic organisms include those organisms that can switch between homeothermic (having body temperature higher than environment) and poikilothermic (having variation in internal body temperature) strategies.

some migratory birds show heterothermy as they decrease their metabolic rate during cold nights to keep their body temperature low. drop in metabolic rate allows increase in production efficiency of birds that reduces the internal body temperature to make it equal to external cold temperature during cold nights.

thus, the correct answer is 'birds allow their temperature drop in order to increase their production efficiency.'

d. all of the above are true.
