Item8 10 points my workCheck My Work button is now enabledItem 8 You have decided to buy a used car. The dealer has offered you two options: (FV of $1, PV of $1, FVA of $1, and PVA of $1) (Use the appropriate factor(s) from the tables provided.) Pay $660 per month for 25 months and an additional $12,000 at the end of 25 months. The dealer is charging an annual interest rate of 24%. Make a one-time payment of $18,850, due when you purchase the car. 1-a. Determine how much cash the dealer would charge in option (a). (Round your answer to 2 decimal places.) 1-b. In present value terms, which offer is clearly a better deal

1. a. $20,199.85

  b. One time payment of $18,850.

Explanation:

1. a. Find the present value of $660 per month (annuity) and $12,000 at the end of 25 months.

Period = 25 months

Interest = 24% / 12 months = 2%

Present value of annuity = 660 * ( 1 - (1 + 2%) ⁻²⁵) / 2%

= $12,885.48

Present value of $12,000 at end of 25 months.

= 12,000 / ( 1 + 2%)²⁵

= $7,314.37

Present value = 12,885.48 + 7,314.37

= $‭20,199.85‬

1.b. Making a one time payment of $18,850 is the better deal.

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.'

yeah its a ok ! just ask the qestoin and someone well answer !
