Tammy’s home cost her $184,000. She lives in an area with a lively real estate market, and her home increases in value by 3. 5
garri49 [273]

The profit to be made when she sells the house is $103,800.

The first step is to determine the value of Tammy's house in 13 years. The formula to be used is:

  • FV = P (1 + r)^n
  • FV = Future value  
  • P = Present value  
  • R = interest rate  
  • N = number of years  

$184,000 x (1.035)^13 = $287,767.92

Profit = value of the house in 13 years - cost of the house

$287,767.92 - $184,000 = 103,767 = $103,800
