See below
Step-by-step explanation:
Decreasing 10% means the car retains 90 % of its value
Value of car = 5000 ( .90)^x where x = number of years
1) Choice A. We can divide both sides by 5 to solve for x.
2) Choice A, yes.
Let’s divide both sides of the equation by 5.
5x=20
5x/5 = 20/5
x = 4
The equations have the same solution, so they are equivalent
