There are 3 Parts. Make sure to answer all 3 Parts. Read the problem and write your
answer for each part. Make sure to label each part: Part A, Part B, and Part C.
Jamie is tracking the growth of a specific bacteria for a science experiment. She
assumes that there are bacteria (B) in a Petri dish at 12:00 midnight. Jamie observes
that the number of bacteria increases by 25 every hour.
Part A. Write an equation that describes the relationship between total number of
bacteria (7) and time (h) in hours, assuming there are (B) bacteria in the Petri dish at h
Part B: If Jamie starts with bacteria in the Petri dish, how many bacteria will be
present after 6 hours?
Part C: If Jamie starts with 5 bacteria in the Petri dish, draw a graph that displays the
total number of bacteria with respect to time from 12:00 midnight (h
0) to
8:00 a.m. (h = 8). Label each axis and label points on your graph at times
h = 0, 1, 2, 3.

Answer:

The answer is below

Step-by-step explanation:

The equation of a linear function is given as:

y = mx + b;

where y, x are variables, m is the rate of change and b is the initial value of variable y.

A) Since there is B bacteria in the Petri dish at 12:00 midnight and the number of bacteria increases after midnight by 25 every hour. Let h represent the time in hours and T represent the total number of bacteria, therefore the equation is:

T = 25h + B

B) Given that B = 5, h = 6, hence:

T = 25(6) + 5 = 150 + 5 = 155 bacteria

C) The equation of the graph is:

T = 25h + 5

The graph was plotted using geogebra online graphing.
