Mrs. Galicia bought a new car for $20,000. This car will depreciate at a rate of 6% per year. Which equation represents this fun ction in terms of x, time.
1 answer:
Answer:
f(x) = 20,000(1 - 0.06)^x -> f(x) = 20,000 = (0.04)^x
Step-by-step explanation:
The equation to get exponential decay is: A = P(1 +- r)^t
A = Account Balance
P = Principle Amount
r = interest rate (decimal)
t = Time (years)
So, if you plug in all the variables with the values represented in the word problem, you get: f(x) = 20,000(1 - 0.06)^x
