The population, P. of bacteria in a culture can be calculated at any time, I, using the equation P = a(2)'. In the equation, the initial number of bacteria is a. The initial number of bacteria in two different cultures were 100 and 125.
How do the two populations compare over time?

Acable company claims that the average household pays $78 a month for a basic cable plan, but it could differ by as much as $20. write an absolute value inequality to determine the range of basic cable plan costs with this cable company. a. |x − 78| ≥ 20 b. |x − 20| ≥ 78 c. |x − 20| ≤ 78 d. |x − 78| ≤ 20
