It is 20%. Assume Josh is 100000 and Jeff is 125000
The formula is (Jeff- Josh)/Jeff * 100 = (25000)/100000 *100 = 20%
The solution for this task is: 13+5=18 18*2=36
Answer:

Step-by-step explanation:
The initial population of bacteria is 800 and we know that this number is quadrupling every hour.
<u>We're going to find a function in terms of t (time) that gives us the population of bacteria at that time.</u>
Since the population is quadrupling every hour the function in terms of t (where t is expressed in hours) is:

Now we need to find the time when there will be 5,120,000 bacterias. This means the time t when f(t) = 5,120,000
So we have 5,120,000 = 

Therefore, the time when there will be 5,120,000 bacterias will be:

G inverse ( g^-1 (x) ) = x-2 over 2. so, g^-1 (3) = 3-2 over 2 = 1/2
