So basically I'm in 8th grade and my teacher gave me this assignment where I would need to find the value of a car that starts off at 22,000 dollars and it decreases by 40% each year. Guessing by the graph that I made it is inverse variation, but I can't seem to find the equation for it. Any tips? Not really asking for the general answer, but if you could help me out that would be nice.
+37095 Car value = 22000(1 - .4)^n n is the number of years -.4 = 40% decrease each year
