2. A car decreases in value by 20% each year. After 2 years, it is worth $12,800. Which equation could be used to find the initial value α?
a. 12800 = α(1.20)^2
b. 12800 = α(0.80)^2
c. 12800 = 0.80(α)^2
d. α = 12800(0.80)^2
a. 12800 = α(1.20)^2
b. 12800 = α(0.80)^2
c. 12800 = 0.80(α)^2
d. α = 12800(0.80)^2
