Explanation
The question indicates we should use a logistic model to estimate the number of plants after 5 months.
This can be done using the formula below;

Workings
Step 1: We would need to get the value of A using the carrying capacity and initial plants that started growing in the yard.
This gives;

Step 2: Substitute the value of A into the formula.

Step 3: Find the value of the constant k
Kindly recall that we are told that the plants increase by 80% after each month. Therefore, after one month we would have;

We can then have that after t= 1month

Step 4: Substitute -k back into the initial formula.

The above model is can be used to find the population at any time in the future.
Therefore after 5 months, we can estimate the model to be;

Answer: The estimated number of plants after 5 months is 130 plants.
Answer:
The answer is d

In this question it is important to look at all the information's that are given. Based on those given information's, the answer to the question can be very easily deduced. Now let us concentrate on the problem in hand.
The number of paychecks that Frances gets in 12 weeks = 6
Then
The number of paychecks that Frances gets in 1 week = (6/12)
= (1/2)
So
The number of paychecks that Frances gets in 52 weeks = (1/2) * 52
= 26
So Frances gets 26 paychecks in 52 weeks.
The break ended at 4pm when he was at 15 km.
The ride ended at 6pm when he was at 45 km.
From 4 to 6pm he rode 45 - 15 = 30 km.
