Acompany had the following purchases and sales during its first year of operations: purchases sales january: 10 units at $120 6 units february: 20 units at $125 5 units may: 15 units at $130 9 units september: 12 units at $135 8 units november: 10 units at $140 13 units on december 31, there were 26 units remaining in ending inventory. using the periodic lifo inventory valuation method, what is the value of cost of goods sold? (assume all sales were made on the last day of the month.)

Ending Inventory under LIFO $3,270

Explanation:

First: in LIFO you always start from the bottom line

subtracting the sales figure for each period.

Notice in nomvember the sales are greater than the amount purchased, so we decrease the september units by the diference

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.'
