If a boat with a value of $23, 000 depreciates at a rate of 18% per year, what is the value
Naily [24]

Using an exponential function, it is found that the value of the car after 5 years will be of $8,527.

<h3>What is an exponential function?</h3>

A decaying exponential function is modeled by:

A(t) = A(0)(1 - r)^t

In which:

  • A(0) is the initial value.
  • r is the decay rate, as a decimal.

For this problem, the initial cost and the decay rate are given as follows:

A(0) = 23000, r = 0.18.

Hence the value of the boat after t years is given as follows:

A(t) = A(0)(1 - r)^t

A(t) = 23000(1 - 0.18)^t

A(t) = 23000(0.82)^t

The value after 5 years will be of:

A(5) = 23000(0.82)^5 = 8527

The value of the car after 5 years will be of $8,527.

How to solve this problem?
Jobisdone [24]

9x - 8y = -11

-9x + 3y = 21

Add the second equation

9x - 8y = -11

+ (-9x) + 3y = 21

-5y = 10

divide both sides by -5

y = -2

substitute y into one of the two equations in the beginning

9x - 8(-2) = -11

9x + 16 = -11

subtract 16 on both sides

9x = -27

divide both sides by 9

x = -3

The answer is (-3, -2)

x = -3

y = -2
