Acompany reports the following beginning inventory and two purchases for the month of january. on january 26, the company sells 440 units. ending inventory at january 31 totals 170 units. units unit cost beginning inventory on january 1 400 $ 3.90 purchase on january 9 90 4.10 purchase on january 25 120 4.20 required: assume the perpetual inventory system is used and then determine the costs assigned to ending inventory when costs are assigned based on the fifo method.

Inventory= $709

Explanation:

Giving the following information:

January 1 400 at $3.90

Purchase on January 9: 90 at $4.10

Purchase on January 25:120 at $4.20

On January 26, the company sells 440 units.

Ending inventory at January 31 totals 170 units.

FIFO (first-in, first-out)

Inventory= 120* 4.20 + 50* 4.10= $709

answer; /// the correct answer is (10) days; /// good luck

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.'
