A population of bacteria doubles every 12 hours initially the population of bacteria is 80 what is the population of bacteria after 30 hours, rounded to the nearest whole number?

I believe it’s 220 because if u do 24 hours that’s 160 which then u can count up to 32 which is 240 which u can take two away

A number of bacteria after 30 hours is 480 bacteria.

The answer is 480 because originally the amount was 80. After 12 hours it doubled to 160. Then after 24 hours have passed, the amount doubled again. So now the amount is 320 bacteria. Then 6 hours passed (half of 12 hours) so then you add half of that amount (160) to 320. 320 plus 160 is 480. So the answer is 480
