A certain kind of bacteria multiplies at a rate of 150 percent per hour. When a person’s blood has 45,000,000 of these bacteria,
DIA [1.3K]
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:

A= A_{o}(1+r)^{t}

Using the values in above equation, we can write:

45000000=100(1+1.5)^{t}  \\  \\ 
450000=(2.5)^{t} \\  \\ 
log(450000)=log((2.5)^{t})  \\  \\ 
log(450000)=t*log(2.5) \\  \\ 
t= \frac{log(450000)}{log(2.5)} \\  \\ 
t=14.21

This means, the person will fall sick after about 14 hours.
