Answer:
y = 100,000 + 3500x
$142,000
Step-by-step explanation:
a. The fixed cost is 100,000 while appreciation is 3, 500/year.
Now after x years, total appreciation equals 3,500 × x = 3500x
The total amount in dollars is thus :
y = 100,000 + 3500x.
b. The value of the house in 12 years.
Since y = 100,000 + 3500x, here, y = ? and x = 12.
y = 100,000 + 3500(12) = 100,000 + 42,000 = $142,000
