12 inches = 1 ft and so 24 inches = 2 ft
Answer:
157286400 bacteria
Step-by-step explanation:
We are given the following in the question:
The bacteria increases 4 times every 6 hours.
Initially there are 150 bacteria.
Thus, we can write the function for number of bacteria after x hours,

We have to find the number of bacteria in 2.5 days.
1 day = 24 hours
Thus,

Putting x = 60 in the above equation, we get,

Thus, there will be 157286400 bacteria in two and a half days.
5×3=15 so 15÷ 3=5, The answer to this question would be is 5.
It would be be the first solution, as it follows the format of (y y1) = m(x-x1)
