Answer:
During the year 2021.
Step-by-step explanation:
As we have a function that defines the annual per capita out-of-pocket expenses for health care, we can work with it.
Knowing that, <u>we clear x</u> (<em>this is the number of years past the year 2000, so it will contain our desired information</em>).
![y=39.6x+543\Leftrightarrow x=\frac{y-543}{39.6}](https://tex.z-dn.net/?f=y%3D39.6x%2B543%5CLeftrightarrow%20x%3D%5Cfrac%7By-543%7D%7B39.6%7D)
Now, as we want to know when are the per capita out-of-pocket expenses for health care predicted to be $1400, and <em>this total is our variable y</em>, then
![x=\frac{1400-543}{39.6}\approx 21.6](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B1400-543%7D%7B39.6%7D%5Capprox%2021.6)
Finally, we know that <u>x is the number of years past the year 2000</u>, so the answer is that during the year 2021, <em>the per capita out-of-pocket expenses for health care are predicted to be $1400</em>.
