Suppose the number of bacteria in a culture is a linear function of time.
a. If there are 2.0 × 108 bacteria in your lab at 5 P.M. on Tuesday, and 5.0 × 108 bacteria the next morning at 9 A.M., find the equation of the line describing the number of bacteria in your culture as a function of time.
b. At what time will your culture have 1.1 × 109 bacteria?
c. The lab across the hall also has a bacterial culture where the number of bacteria is a linear function of time. If they have 2.0 × 108 bacteria at 5 P.M. on Tuesday, and 3.4 × 108 bacteria the next morning at 9 A.M., when will your culture have twice as many bacteria as theirs?
