Question

Olivia is testing the effectiveness of two antibiotics on the growth of bacteria in her lab. She has two Petri dishes that contained the same number of bacteria at the start of the experiment. After treating each dish with an antibiotic and then waiting a period of one hour, she calculates the number of bacteria remaining and records the results in the table below.

Answer 1

The initial problem stated that “She calculated the number of bacteria REMAINING and records the results below” which means A or the first option is the correct answer because it has less bacteria remaining due to the fact that 5 is the exponent ( has less bacteria ).
