Question

Bacteria colonies can increase by 45% every week. If

you start with 200 bacteria microorganisms, how
large would the colony be after 35 days?
Lastly, solve and round to the nearest whole number.
Future Amount = 200(1+0.45)5
Future Amount = [?] microorganisms
Enter

Answer 1

I = 200
r = 45% = 45 / 100 = 0.45
t = 3517 = 5
Substituting,
Future amount = (200) (1 + 0.45)^5
=1281.95

Answer 2

The future amount of the bacteria colony after 35 days, rounded to the nearest whole number, is approximately 4800 microorganisms.

To calculate the size of the bacteria colony after 35 days, we can use the formula for exponential growth:

`\[ \text{Future Amount} = \text{Initial Amount} * (1 + \text{Growth Rate})^{\text{Number of Time Periods}} \]`

In this case, the initial amount is 200 bacteria microorganisms, the growth rate is 45% (or 0.45), and the number of time periods is 35 days divided by 7 (since there are 7 days in a week).

Let's calculate it step by step:

1. Calculate the number of time periods in weeks:

`\[ \text{Number of Time Periods} = \frac{35 \text{ days}}{7 \text{ days/week}} \]`

2. Calculate the future amount using the formula:

`\[ \text{Future Amount} = 200 * (1 + 0.45)^{\text{Number of Time Periods}} \]`

3. Round the result to the nearest whole number.

Now, let's perform these calculations.

Let's calculate it step by step:

1. Calculate the number of time periods in weeks:

`\[ \text{Number of Time Periods} = \frac{35 \text{ days}}{7 \text{ days/week}} = 5 \text{ weeks} \]`

2. Calculate the future amount using the formula:

`\[ \text{Future Amount} = 200 * (1 + 0.45)^(5) \]`

3. Round the result to the nearest whole number.

Now, let's calculate it.

Let's calculate it step by step:

1. Calculate the number of time periods in weeks:

2. Calculate the future amount using the formula:

`\[ \text{Future Amount} = 200 * (1 + 0.45)^(5) \]`

3. Round the result to the nearest whole number.

Now, let's calculate it.
