a scientist counts 35 bacteria present in a culture and finds that the number of bacteria triples each hour. the function y = 35 • 3x models the number of bacteria after x hours. estimate when there will be about 550 bacteria in the culture.
i think it's about 2.5 hours.

about 5.5 hours
about 4.5 hours
about 3.5 hours

The answer to your question is about 5.5 hours.

Step-by-step explanation:

The equation is y = 35(3x)

Data

# of bacteria = 550 = y

time = ? h

    Then    550 = 35(3x)                         substitution

                 550 = 105x                           simplifying

                x = 5.23 h.

since both sides equal, there are infinitely many olutions.
