The table below gives the value of a car over two years.Using an exponential best-fit model, after how many years is the car valued at 25% of the original value?

Year 0 0.5 1.0 1.5 2.0

Value ($)15,500.00 14,560.00 13,911.20 12,969.66 12,204.09

Exponential equation will be...

Y = 15517.9432*(0.888^X)

Y = Value

X = year

for Y = 15000/4 = 15517.9432*(0.888^X)

X=>11.95 Years (approximately 12 years)
