At the peak of her career, 40 million people recognized Britney Spears, but that number has decreased by 10% each year. Which of the following equations models the number of people, y, who still recognize her after x years?
A
y = 40,000,000(0.9)x
B
y = 40,000,000(0.01)x
C
y = 0.9(40,000,000)x
D
y = 0.1x + 40,000,000
E
y = 0.01(40,000,000)x
