Guided Practice The value of a car depreciates every year. Suppose you buy a new car for $17,000, and each year its value is only 90% of what it was the previous year. Write an equation that represents the value of the car, y, after x years.

A.
y=0.90 · 17,000xy equals 0.90 times 17,000 superscript x baseline

B.
y=17,000 · 0.90xy equals 17,000 times 0.90 superscript x baseline

C.
y=17,000 · 0.10xy equals 17,000 times 0.10 superscript x baseline
