A.CED.1 You bought a car for $5,000. Each year it depreciates in value by 8.5%. Which equation can be used to find the value, v, of the car, x years after it was purchased?

• $v\ =5000\left(1\cdot0.085\right)^x$

• $v\ =0.085\left(5000\right)^x$

• $v\ =5000\left(1-0.085\right)^x$

• $v\ =5000\left(1+0.085\right)^x$
