79 laboratories raise the bacterium, the laboratory have 48 culture dishes on average, which has about 25,075 bacteria each. How many bacteria are there approximately?

A. 10^7
B. 10^8
C. 10^9
D. 10^10
E. 10^11

-> Due to approximately, 79=80, 48=50, 25,075=25,000 are derived, which makes (79)(48)(25,075)=(80)(50)(25,000)=10^8. The answer is B.
