Hi, there--
THE PROBLEM:
Brandon works in a scientific laboratory where he observed that his bacteria culture doubles
in size every 30 minutes. If there were 2,000 bacteria in the Petri dish at 10 a.m., how many
will there be at 12p.m ?
A SOLUTION:
I'll help you get started. Since the bacteria double each 30 minutes, we can construct a
table and write out the bacteria
counts.
TIME ------------BACTERIA COUNT (double each time)
10:00am ---------2000
10:30am ---------4000
11:00am ---------???
11:30am ---------???
12:00pm ---------???
Hope this helps!
