Question

The Count of bacteria is increasing at a 2.5 % per hour. Find the bacteria at the end of 2 hours if it was initially 450000

Answer 1

Answer:

476781.25

Step-by-step explanation:

Initial bacteria = 450000

bacteria increases 2.5% every hour.

So, in the first hour, it will increase by 2.5% of 450000

2.5/100 * 450000 = 25/1000 * 450000

= 25 * 450 = 11250

So, after 1 hour, the bacteria will be 450000 + 11250 = 461250

Now, for the second hour, the bacteria will increase by 2.5% of 461250

2.5/100 * 461250  =  25/1000 * 461250

= 1/40 * 461250

= 11531.25

So, after 1 hour, the bacteria will be 461250 + 11531.25 = 476781.25

∴ After 2 hours, the bacteria will be 476781.25
