Miguel, a recent 22-year old college graduate, wants to retire a millionaire. How much will he need to set aside annually to achieve his goal, assuming he plans to retire at 65 and he can earn a 10% annual return on his investment?

Answer

Miguel must set aside $62,745 annually

Explanation

N = Number of years till Miguel would retire = 43 years

FV = Future Value = $1,000,000

r = Interest rate = 10%

PMT = Annual payments (at the ending of the year) = ?? The question asks us to calculate this

We would use the future value ordinary annuity formula to calculate PMT

FV = PMT

1000000 = PMT

PMT ≅ $62,745

Miguel must set aside $62,745 annually

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.'
