How long will it take for the culture to grow to 900,000 bacteria? Round to the nearest tenth of an hour and include units.

There are initially 340 cells present in a colony of bacteria. This strain of bacteria grows by 22% every 3.5 hours. Assuming that this growth continues in this man- ner, determine the following. How many bacteria cells will be present in the colony after 24 hours? How long will it take for the colony to reach 5000 bacteria cells? Round each response to the nearest whole number. bacteria cells hours.
