Brilliant_brown [7]
1.25c=12.5
Let's look at the equation. We need C by itself. The only way we can do so is by dividing each side by 1.25
1.25c=12.5
1.25c÷1.25= c
12.5÷1.25= 10
C=10
The value of C in the equation is 10.

podryga [215]

Answer: 5489

Step-by-step explanation:

Given the following :

Growth rate (r) = 19% per hour

Sample culture in population = 2300

Size of sample after 5 hours =?

Using the exponential relation:

P = Po * r^t

P = population after 5 hours

Po = Initial sample population

t = time

P = 2300 * (1 +19%)^t

P = 2300 ×(1 + 0.19) ^5

P = 2300 * 1.19^5

P = 2300 * 2.3863536599

P = 5488.61341777

P = 5489 (nearest integer)
