A culture started with 2000 bacteria. After 4 hours, it grew to 2,200 bacteria. Predict how many bacteria will represent after 9

S_A_V [24]

Y=2000* $e^{k*t}$

2200=2000* $e^{k*4}$

$e^{k}= ( \frac{22}{20} )^{(1/4)}$ 

so,
y at t=8 is 2000*( $( \frac{22}{20} )^{(1/4)}$ )^8
y = 2000(22/20)^2=2000*1.21=2420 thats the answer i hope.
