Two vampires come to a small town of 600 people. After that, the number of vampires increased by 75% each week. Which equation describes the number of vampires in the town (where t represents time in weeks)?

Hint: When an amount is getting smaller, its called a decay function. An exponential decay function is (1- rate\right)^{time}

A. f(t)=600(1.75)^t
B. f(t)=600+.75t
C. f(t)=2(0.75)^t
D. f(t)=2(1.75)^t
