The number of bacteria increased overnight by 325%. If there were 35,000 yesterday, how many bacteria were there this morning?

To find out how many bacteria were present this morning after a 325% increase, you can follow these steps:

1. **Calculate the increase in the number of bacteria:**

\[
\text{Increase} = 325\% \times 35,000
\]

First, convert 325% to a decimal:

\[
325\% = 3.25
\]

Now multiply:

\[
\text{Increase} = 3.25 \times 35,000 = 113,750
\]

2. **Add the increase to the original number of bacteria:**

\[
\text{Total number of bacteria} = 35,000 + 113,750 = 148,750
\]

So, there were **148,750** bacteria this morning.

Here are five related questions to explore:
1. What would be the total number of bacteria if the increase was 200%?
2. How do you calculate a 50% decrease in a population of 80,000 bacteria?
3. If a population grows by 400%, what does that mean in terms of multiplication?
4. How many bacteria would be present if there was a 150% increase from 60,000?
5. What would be the result if the bacteria increased by 25% instead of 325%?

**Tip:** When dealing with percentage increases or decreases, it's important to add or subtract the original amount to get the total value.

Discover how to calculate bacteria growth with a 325% increase from an initial count of 35,000. Follow a step-by-step solution involving percentage increase calculations. Suitable for students in Grades 5-7.
