Step-by-step explanation:
The exponential decay function is
where a is the initial value of the car, b is the rate of decay, and t is the time in years. Our rate of decay can also be written as (1 - r) where r is the depreciation in decimal form. Our equation looks like this:
which simplifies to
Now we can solve our problem for any number of years you'd like. We've been tasked to find the value of the car after 3 years, so:
which simplifies a bit to:
so
v(t) = 8043.57
Answer:
<h3>The answer is # 4200</h3>Step-by-step explanation:
A discount of 40% was allowed on the price
To find the price after the discount first calculate the discount and subtract it from the original price
That's
= 2800
So the price after the discount is
#7000 - #2800
Which is
<h3># 4200</h3>Hope this helps you
