Bayest manufacturing corporation uses a predetermined overhead rate based on direct labor-hours to apply manufacturing overhead to jobs. last year, the corporation worked 56,000 actual direct labor-hours and incurred $352,000 of actual manufacturing overhead cost. the corporation had estimated that it would work 60,000 direct labor-hours during the year and incur $330,000 of manufacturing overhead cost. the corporation's manufacturing overhead cost for the year was:

$ 44000

Explanation:

Given:

Actual overhead manufacturing cost, Ac = $ 352000

Actual direct labor hours, Ah = 56000

Estimated manufacturing overhead cost, Ec = $ 330000

Estimated direct labor hour, Eh = 60000

Now,

Predetermined Overhead Rate = Ec/Eh

on substituting the values in the above formula we get

= $ 330000/60000 = 5.5

also,

Underapplied Overhead = Ac + (Ah × Predetermined Overhead Rate)

on substituting the values in the above formula we get

Underapplied Overhead = 352000 - (56000 × 5.5)

or

Underapplied Overhead = $ 44000

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.'
