Answer:
16
Step-by-step explanation:
just use a mean absolute deviation calculator next time
The equation of the value of the car over a year is 2357.14x + y = 33,000. Then the value of the car 4 years after it was purchased is $23571.43.
<h3>What is the linear system?</h3>
A Linear system is a system in which the degree of the variable in the equation is one. It may contain one, two, or more than two variables.
A new car is purchased for $33,000 and overtime its value depreciates by one half every 7 years.
Then the value of the car is given by the linear equation. Then the line is passing through (0, $33,000) and (7, $16,500). Then we have
Let y be the value of the car and x be the number of years. Then we have
![\rm y \ - \ 33000 \ \ = -\dfrac{16,500}{7} (x-0)\\\\y+2357.14x = 33000](https://tex.z-dn.net/?f=%5Crm%20y%20%5C%20%20%20-%20%5C%20%2033000%20%5C%20%5C%20%3D%20-%5Cdfrac%7B16%2C500%7D%7B7%7D%20%28x-0%29%5C%5C%5C%5Cy%2B2357.14x%20%3D%2033000)
Then the value of the car 4 years after it was purchased, to the nearest hundred dollars will be
![\begin{aligned} \rm y +2,357.14 \times 4 &= 33,000\\\\\rm y + 9,428.57 &= 33,000\\\\\rm y &= 23,571.43 \end{aligned}](https://tex.z-dn.net/?f=%5Cbegin%7Baligned%7D%20%5Crm%20y%20%2B2%2C357.14%20%5Ctimes%204%20%26%3D%2033%2C000%5C%5C%5C%5C%5Crm%20y%20%2B%209%2C428.57%20%26%3D%2033%2C000%5C%5C%5C%5C%5Crm%20y%20%26%3D%2023%2C571.43%20%5Cend%7Baligned%7D)
