You have recently won the super jackpot in the Washington State Lottery. On reading the fine print, you discover that you have the following two options: a. You will receive 31 annual payments of $250,000, with the first payment being delivered today. The income will be taxed at a rate of 28 percent. Taxes will be withheld when the checks are issued.
b. You will receive $530,000 now, and you will not have to pay taxes on this amount. In addition, beginning one year from today, you will receive $200,000 each year for 30 years. The cash flows from this annuity will be taxed at 28 percent. Using a discount rate of 6.25 percent, which option should you select?

should choose option a

Explanation:

option a)

annuity due, 31 payments of $180,000 per year, 6.25% discount rate

Present value = $180,000 x 14.40432 (PV annuity due factor, 6.25%, 31 periods) = $2,592,726

option b)

$500,000 today + ordinary annuity, 30 periods, 6.25%, $144,000

present value = $500,000 + ($144,000 x 13.40432 [PV annuity factor, 6.25%, 30 periods)] = $2,430,222

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.'
