Question

a culture started with 2,000 bacteria. after 6 hours, it grew to 2,400 bacteria. predict how many bacteria will be present after 16 hours. round your answer to the nearest whole number

Answer 1

Hello!

First you have to find how much bacteria grows every hour

In 6 hours it went from 2000 to 2400 this is a difference of 400

This means that 400 bacteria grew in 6 hours

Divide the amount of bacteria grew by the amount of hours to get how much grows an hour

400 / 6 = 66.666...

Multiply this by the amount of hours that passed

66.666 * 16 = 1066.6

Round to the nearest whole number

1067

Add this to the amount of bacteria that was at the start

2000 + 1067 = 3067

The answer is 3067 bacteria

Hope this helps!
