Conclusion of importance of source document

Prepare a depreciation schedule assuming actual mileage was: 2017, 38,500; 2018, 31,000; 2019, 31,000; and 2020, 42,000. (Round cost per unit to 2 decimal places, e.g. 15.25 and all other answers to 0 decimal places, e.g. 5,275.)

Explanation:

Answer #1

Depreciation cost per unit = ( Cost - Salvage value ) / Expected miles to be driven = ( 215150 - 7100 ) / 1425001.46per mile

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.'

credit history is used by lenders to determine whether you are a 'risky' person to give their money to.

having a short history provide very little data for the lenders. they wouldn't be able to determine your credit behavior from such a small samples. even if they are perfect.

having long credit history with few blemishes provide larger and more accurate data for the lenders to predict your credit behavior.
