(35 + 47 + 42 + x) / 4 = 50
(124 + x) / 4 = 50....multiply both sides by 4, cancelling the 4 on the left side.
124 + x = 50 * 4
124 + x = 200
x = 200 - 124
x = 76 <===
Given:
The growth of a sample of bacteria can be modeled by the function
![b(t)=1001.06t](https://tex.z-dn.net/?f=b%28t%29%3D1001.06t)
where, b is the number of bacteria and t is time in hours.
To find:
The number of total bacteria after 3 hours.
Solution:
We have,
![b(t)=1001.06t](https://tex.z-dn.net/?f=b%28t%29%3D1001.06t)
where, b is the number of bacteria and t is time in hours.
Substituting t=3, we get the number of total bacteria after 3 hours.
![b(3)=1001.06(3)](https://tex.z-dn.net/?f=b%283%29%3D1001.06%283%29)
![b(3)=3003.18](https://tex.z-dn.net/?f=b%283%29%3D3003.18)
Number of bacteria cannot be decimal value. So, approximate the value to the nearest whole number.
![b(3)\approx 3003](https://tex.z-dn.net/?f=b%283%29%5Capprox%203003)
Therefore, the number of total bacteria after 3 hours is about 3003.
You’re answer it would be D.5 because it is the smaller than the other sides
