An experiment starts with 30 bacteria. After 4 hours, there are 135 bacteria. How long will it take for the bacteria population to reach 4,500? Round to the nearest tenth of an hour. You must show your work.
Well in order to figure out the rate per hour we would do 135 minus 30 and get 105 then divided that by 4 and get 26.25 then divided 4500 by 26.25 and get 171.4 hours
