The growth of bacteria is modeled as P = P0ert. In a sample culture, the bacteria grows at a rate of 6 percent per minute. If th

xxTIMURxx [149]

Initial number of Bacteria = Po = 1000
Growth rate = r = 6% = 0.06
We want to find the number of Bacteria after 5 minutes.

Using the given equation, we can write:

$P= P_{o}e^{rt} \\ \\ 
P=1000(2.718)^{0.06*5} \\ \\ 
P=1000(2.718)^{0.3} \\ \\ 
P=1350$

Rounding of to nearest integer, the number of Bacteria after 5 minutes will be 1350. So option C gives the correct answer

Sara has $1.30 less than double what Billy does. Sara has $53.72. How much money does Billy have?

lilavasa [31]

Answer:

Billy has $27.51

Step-by-step explanation:

First let's set up an equation to solve this problem.

Assign a variable to Billy's amount. Let's make it x.

Then we just interpret the problem and solve:

2x - 1.30 = 53.72

+1.30 +1.30

----------------------------

2x = 55.02

(Divide by 2 on both sides)

----------------------------

x = $27.51

2x = Billy's amount doubled

2x - 1.30 = Taking away 1.30 from double Billy's amount

53.72 = Sara's amount
