(the tricky word here is "triple every 12 hours" not "add every 12 hours")
so you dont have to multiply 4x3=12
INSTEAD you have to increase the power of 3 to 4
now you have 3^4=81 and 81*50 = 4050 is the total bacteria in 2 days
(the number 4 is from 48hours/12hours= 4 times the bacteria will triple)
from the word itself "4 times bacteria will triple"
so if you use the A solution you would still get the same answer with the B solution
(REMEMBER THAT doing 4x3=12 is WRONG! this will get you the answer of 600 which is 100% WRONG! your only saying that in total of 48 hours the bacteria will be 4 times than the t=0 which is not the main point of the problem)

150 for every 12 hours. there are four 12 hours in 2 days. 150×4=600. mali po iyong sagot

okay lets make this clear you cant multiply it by 4 since the keyword here is "triple every 12 hours" you have to power it NOT multiply that means 3^4 = 81 then 81*50 = 4050, think before you comment make reassurance and use ur comprehensive reading carefully

good Lord talaga. because there are two days thus 48 hours

Also its a "bacteria" bacteria multiplies "itself" so it is not questionable why.. note that math is solved with a good comprehension and common sense

understand the statement, I know its 2 days = 48 hours thats 4 times the bacteria will triple then surely every 12 hours it multiplies by 3 and you shouldnt take shortcut to multiply by 4 you must do it individually, basta 100% tama tong answer ko

Answer:
A.
thats ez 50*3 = 150 for the 12th hour
150*3= 450 for the first day
450*3= 350 for 1 day and 12 hours
350*3= 4050 bacteria in 2 days
