Question

Bacteria colonies increase by 37% every 2 days. If you start with 55 microorganisms, how large would the colony be after 10 days

Answer 1

The number of microorganisms that I will have after 10 days would be: 245.41 microoganisms.

How to calculate the number of microorganisms that I will have after 10 days?

To calculate the number of microorganisms that I will have after 10 days, I must perform the following operations:

We need to find 37% of 55 as shown below:

• 55 ÷ 100 = 0.55
• 0.55 x 37% = 20.35
• 55 + 20.35 = 75.35

So after 2 days I will have 75.35 microorganisms.

• 75.35 ÷ 100 = 0.75
• 0.7535 x 37% = 27.87
• 75.35 + 27.87 = 103.22

On the fourth day I will have: 103.22 microorganisms.

• 103.22 ÷ 100 = 1.0322
• 1.0322 x 37% = 38.19
• 103.22 + 38.19 = 141.41

On the sixth day I will have 141.41 microorganisms.

• 141.41 ÷ 100 = 1.4141
• 1.4141 x 37% = 52.32
• 141.41 + 52.32 = 193,73

On the eighth day I will have 193.73 microorganisms.

• 193.73 ÷ 100 = 1.9373
• 1.9373 x 37% = 71.68
• 193.73 + 71.68 = 265.41

On the tenth day I will have 245.41 microoganisms.
