The number of bacteria in a culture is expected to grow 82% per hour over the next several hours. The predicted change in the number of

bacteria can be represented by P= 120(1.82) where P is the predicted number of bacteria t hours from now.
To the nearest tenth of a percent, by what percent is the number of bacteria expected to grow by each minute?
O .1%
O 1.0%
O 1.1%
O 1.4%

If my simplification is valid the answer is:

1.4 % growth each minute

I don’t feel like the representation
P = 120(1.82) is important in this certain problem.

So P the predicted number of bacteria is not practical with this problem.

Use the 82% per hour and divide it by 60 because there are 60 minutes in an hour.

When doing this you find the rate in which bacteria grows which is about 1.4%.

The prediction is about 1.82 percent for 120 something it’s not clarified, but I’m guessing that’s minutes.

So you can prove that the prediction is over the rate in which bacteria grows per minute.
