Answer:
y = r / (k+v)
Step-by-step explanation:
First, you use the distributive property and take out y: y(k+v)=r
Then you divide both sides by (k+v): y<u>(k+v)/(k+v)</u> = r/(k+v)
Finally you get y = r / (k+v)
We will see that the percentage in which the price decreases is 90%, thus the age is 90 years.

How old is Andrés?
We know that the percentage in which the price decreases is equal to the age of Andrés.
We can write:
P = $4,000 = $40,000*(1 - k)
Where k is the percentage in decimal form.
Solving for k:
k = ($40,000 - $4,000)/$40,000 = 0.9
To obtain the percentage, we multiply by 100%.
0.9*100% = 90%
We conclude that Andrés is 90 years old.
