50 hours cause you take 150 divided it by 3
10 times 20,000 equals 200,000. So the answer is C, the value of the 2 is 10 times greater
Initial number of Bacteria = Ao = 100
Number of Bacteria which make the person ill = A = 45,000,000
Growth rate = r = 150% = 1.50
The equation model for this situation is:

Using the values in above equation, we can write:
This means, the person will fall sick after about 14 hours.
Since 111 is greater than 33, I will assume that you meant 11 votes for a candidate. Also, assuming that each student can vote only once, the answer would be
11/33 x 100=33.333333...
About 33.333 of the voters voted for candidate a.
