SOMEONE PLEASE HELP ME WITH THIS QUESTION !!!

Answer 1

Answer:

$700

Step-by-step explanation:

Given that:

Cost of desktop PC 10 years ago = $6000

Cost of desktop PC 2 years ago = $300

Linear model applies.

To find the rate of decrease per year, we need to find the slope.

One quantity is cost of PC here and second quantity here is number of years.

$\text{Rate of decrease per year = }\dfrac{\text{Change in Price}}{\text{Change in Number of years}}$

$\Rightarrow \dfrac{6000-300}{10-2}\\\Rightarrow \dfrac{5700}{8}\approx \bold{\ 700}$

So, the answer is:

There is a decrease of $700 per year.

OR

Rate of decrease per year is $700.
