The answer is <span>C.) 2
The general form of formula is
y = a </span><span>• r^x
y - the total number of bacteria after x period of time
a - the initial number of bacteria
r - growth rate
x - period of time
Let's compare:
</span>y =    a   • r^x
<span>y = 280 • 2^x
Since r = 2, the growth rate is C.) 2</span>
