Ben has $500 in his savings account and the bank pays an interest rate of 10 percent a year. The inflation rate is 6 percent a year. The government taxes the interest that Ben earns on his deposit at 20 percent. Calculate the nominal after-tax interest rate and the real after-tax interest rate that Ben earns.

Explanation:

The Nominal rate is 10%

Inflation rate is 6%

And Tax rate is 20%

Nominal after-tax interest rate

= Nominal rate (1 - tax rate)

= 10% ( 1 - 0.2)

= 8%

Real After-Tax Interest Rate

= Nominal after-tax interest rate - inflation rate

= 8% - 6%

= 2%

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.'

the answer is     d. in our global economy, most job growth will be in services, but manufacturing jobs will exist, too.
