Answer:
$42,890
Step-by-step explanation:
The standard form for an exponential equation is

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:

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:
or, after some simplification:

First rais .96 to the 12th power to get
A(t) = 70,000(.6127097573)
and then multiply.
A(t) = $42,890

You present a statement but do not explain what the goal is here.
My reaction to your statement is that it is false. It'd make far more sense to state that earnings are positively correlated to the number of years of college that a student has completed.
