There are 3000 bacteria in a day, if the number of bacteria double per 2 days , how many bacteria can we expect to have in 15 days??

My result was 44,999.99 which if rounded is 45,000,am i accurate? ?

1 answer

amount = 3000(2)^(t/2) , where t is the number of days
= 3000(2)^(15/2)
= 543,058

How did you get 45,000 ?
