Question
The Montag Family purchased a house in 2020 and expects its value (in thousands of dollars) t
years in the future will be well-modeled by the function V(t)=310(1.08)
. By what percentage does the model predict the house will increase in value each year?
Expert Solution
Step 1
The rate at which value of the purchased house is increasing = r
The growth factor = b
Time = t
The initial value of house =P
The final value of the house after t hours = A
The well model function of the value of a house is given as,
V(t) = 310 (1.08)^t
This is the exponential model where
A = P b^t
Here, p = 310, A = V(t) and b = 1.08
