You buy a new computer for $2100. The computer decreases by 50% annually. What is the exponential equation that best describes this situation?

y=2100(.50)ty=2100\left(.50\right)^t

y=2100(1.5)ty=2100\left(1.5\right)^t

y=.50(2100)ty=.50\left(2100\right)^t

y=1.5(2100)ty=1.5\left(2100\right)^t

The value of a car purchased for $20,000 decreases at a rate of 12% per year. What will be the equation that best represents this situation?

y=20,000(1.12)ty=20,000\left(1.12\right)^t
