A physical count of merchandise inventory on July 30 reveals that there are 170 units on hand. Using the FIFO inventory method, the amount allocated to ending inventory for July is

$3,502

Explanation:

When using FIFO, It means that the earliest goods were sold first which means that the later goods would be the ones in the ending inventory.

The 170 units on hand would therefore include:

Ending inventory = (22 * 51) + ((170 - 51) * 20)

= 1,122 + (119 * 20)

= 1,122 + 2,380

= $3,502

explanation:

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.'
