Shelly is a biologist who wants to determine the growth rate of a strain of bacteriashelly puts 85 bacteria into a controlled environment and waits 4 hours. when shelly checks 4 hours later, there are 850 bacteria. what is the hourly growth rate of the bacteria?
write your answer as a numeric value, such as: 345.59 round your answer to the second decimal place.

The hourly growth rate of bacteria is 191.25

Solution:

Given that, initially Shelly put 85 bacteria and waits 4 hours

Amount of bacteria after 4 hours = 850

Now, number of bacteria increased = 850 bacteria – initial 85 bacteria  

Number of increased bacteria = 850 – 85 = 765 bacteria.

So, 765 bacteria were produced in 4 hours.

So hourly growth rate( per hour) can be found out by as follows:

Hence, the hourly growth rate of bacteria is 191.25

the answer is simply just 6n add the two together as they have an n
