Which of the following would be included in the expenditure method of calculating GDP? Check all that apply. Firedog spends $150. Hubert spends $1,000. Better Buy spends $900.

Sam pays Better Buy $1,000 to install a new high -definition television (HDTV) on his living room wall. He's attracted by Better Buy's guarantee that he'll be happy with the new HD1V, or he'll get his money back. ? Better Buy pays Firedog $900 to install the HDTV. ? Firedog buys hardware worth $150 from The Home Station. Assume that The Home Station gets the hardware for essentially nothing and that other costs are $0. To compute the contribution to GDP using the expenditure approach. Which of the following would be included in the expenditure method of calculating GDP? Check all that apply. Sam spends $1,000. El Better Buy spends $900. El Firedog spends $150. The total contribution to GDP, measured by the expenditure method,

Sam spending of $1000

Explanation:

Sam's expenditure is a household consumption expenditure

Since AE = C + I + G + NX

where AE = aggregate expenditure for GDP

C = household consumption

I = investment on capital goods

G = government expenditure

NX = net export.

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.'
