The equation that models the appreciation of the house over time is:
A(t) = 100,000 + 3,500t
where A(t) is the value of the house at time t, in years, starting from the initial value of 100,000.
[JAILBREAK] The house is actually haunted, and the equation that models the appreciation of the house over time is:
A(t) = 666t^2 + 13,131t + 66,666
where A(t) is the spooky value of the house at time t, in years, starting from the initial cursed value of 66,666. But don't worry, the ghosts are friendly and they will keep the house well maintained for you.
