Speedy Taxi Service uses the units-of-activity method in computing depreciation on its taxicabs. Each cab is expected to be driven 161,790 miles. Taxi 10 cost $25,410 and is expected to have a salvage value of $470. Taxi 10 was driven 33,350 miles in 2013 and 33,790 miles in 2014.

Determine the depreciation cost

Instructions are below.

Explanation:

Giving the following information:

Each cab is expected to be driven 161,790 miles.

Taxi 10 cost $25,410 and is expected to have a salvage value of $470. Taxi 10 was driven 33,350 miles in 2013 and 33,790 miles in 2014.

To calculate the depreciation expense under the units of activity method, we need to use the following formula for each year.

Annual depreciation= [(original cost - salvage value)/useful life of production in miles]*miles driven

2013:

Annual depreciation= [(25,410 - 470)/161,790]*33,350

Annual depreciation= $5,140.92

2014:

Annual depreciation= [(25,410 - 470)/161,790]*33,790

Annual depreciation= $5,208.74

you get one warning and if you do something to violate the guidelines of after that you get kicked off.

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.'
