A culture started with 2,000 bacteria. After 2

hours, it grew to 2,400 bacteria. Predict how

many bacteria will be present after 10 hours.

Round your answer to the nearest whole

number.

P = Aekt

Answer: In 10 hours, 4000 bacteria will be present.

Step-by-step explanation:

Given that 2000 bacteria grew to 2400 in 2 hours,

growth / increase rate = 2400 - 2000

= 400 bacteria increase in 2 hours

Per hour is therefore 400/2 = 200 bacteria increase per hour

If the bacteria increases by 200 per hour

If 200 = 1 hour

X = 10 hours

We cross multiply:

X = 200 x 10

X = 2000

Therefore, a culture with 2000 bacteria at the same growth rate will have increased by additional 2000 in 10 hours

So, after 10 hours, number of bacteria will be 2000 + 2000 = 4000 bacteria
