Answer:
(E). 19
Step-by-step explanation:
Let original population of each colony be P.
We have been given that a certain bacteria colony doubles in size every day, so bacteria colony is growing exponentially. After x days, the population of bacteria would be:
The population after 19 days will be for each colony.
The total population of both the colonies at that point will be which is what the habitat's limit is.
Therefore, it will take 19 days for two bacteria colonies to reach the habitat's limit and option E is the correct choice.

Answer: Option A
===================================================
Explanation:
If she goes with option A, then she works two days for 8 hours a day. In total she works 8+8 = 16 hours. At $7 an hour, she earns 16*7 = 112 dollars.
If she goes with option B, then she earns 5% on the total of 200*10 = 2000 dollars. So 5% of 2000 = 0.05*2000 = 100 dollars is earned.
Option A yields her $112 while option B yields $100. She earns more with option A.
