In general, you're calculating the magnitude of average velocity. In fact, speed is a vector, and as such it also has a direction and orientation.

<u>Answer:</u>
$593.26
<u>Step-by-step explanation:</u>
We know that the price of the laptop is $2500 and each year its resale value decreases by 25%. It means that 100 - 25 = 75% of the value is retained every year for the resale.
So, the resale value for 1st year =
$1875
for 2nd year =
$1406.25
for 3rd year =
$1054.7
for 4th year =
$791.01
for 5th year =
$593.25
Or we can use the following formula to find its resale value after 5 years:
$593.26
