A car, originally valued at 70,000 in 2006 depreciates exponentially at a rate of 4% each year. Round the expected value of the

lora16 [44]

Answer:

$42,890

Step-by-step explanation:

The standard form for an exponential equation is

$y=a(b)^x$

where a is the initial amount value and b is the growth rate or decay rate and t is the time in years. Since we are dealing with money amounts AND this is a decay problem, we can rewrite accordingly:

$A(t)=a(1-r)^t$

where A(t) is the amount after the depreciation occurs, r is the interest rate in decimal form, and t is the time in years. We know the initial amount (70,000) and the interest rate (.04), but we need to figure out what t is. If the car was bought in 2006 and we want its value in 2018, a total o 12 years has gone by. Therefore, our equation becomes:

$A(t)=70,000(1-.04)^{12}$ or, after some simplification:
