Answer: The buyer will save 18k dollars

Step-by-step explanation:

He is saving 18k becuase that is 8 percent of 21k

Answer:

  • The 20 year 8% year loan is more economical
  • The buyer will save $159650

Step-by-step explanation:

Use the given formula to calculate each option and compare.

Option 1

  • P = $210000
  • r = 8.5% = 0.085
  • t = 30
  • n = 1

Find the PMT:

  • [tex]P(r/n)/(1-(1+r/n)^{-nt})=210000*(0.085)/(1-(1+0.085)^{-30})=19541[/tex]

Find the total interest amount:

  • 30*$19581 - $210000 = $377430

Option 2

  • P = $210000
  • r = 8% = 0.08
  • t = 20
  • n = 1

Find the PMT:

  • [tex]P(r/n)/(1-(1+r/n)^{-nt})=210000*(0.08)/(1-(1+0.08)^{-20})=21389[/tex]

Find the total interest amount:

  • 20*$21389 - $210000 = $217780

We see option 2 reveals less interest amount, so is more economical.

Saving on interest:

  • $377430 - $217780 = $159650
