Answer:
After 3 years ,the house will worth : $112 745.38968
Step-by-step explanation:
Method 1:
the house will worth after 1 year :
[tex]90000+90000\times \frac{7.8}{100} =97020[/tex]
the house will worth after 2 years :
[tex]97020+97020\times \frac{7.8}{100} =104587.56[/tex]
the house will worth after 3 years :
[tex]104587.56+104587.56\times \frac{7.8}{100} =112745.38968[/tex]
Method 2:
we consider the geometric sequence Un of :
First term U₀ = 90000
common ratio q = 1 + (7.8/100) = 1.078
Then
[tex]U_{3}=q^{3}\times U_{0}[/tex]
Then
[tex]U_{3}=(1,078)^{3}\times 90000=112745.38968[/tex]
