I think it might be D. I'm just giving an educated guess.
The time it would take for the bacteria to reach 1119 is 5.83 hours
<h3>Calculations and Parameters:</h3>
Given the function:

- Initial amount= 50
- amount after 3 hours= 80
To find the exponential growth;
80 = 

If there is a constant growth, then to get to 1119:
1119= 
3.8 = 0.533*t
t= 5.83 hours
Therefore, it would take 5.83 hours for the bacteria to increase to 1119.

Answer:
A. 156 students are in choir
Step-by-step explanation:
It states that for every 3 students in choir equals 1 student in band which give you the equation 1x3. So if band has 52 students then your new equation is 52x3 which is 156! Hope this helps!:)
