After 8 weeks your accounts have the same balance.
Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
You have $22 in your bank account and deposit $11.50 each week.
And, At the same time your cousin has $218 but is withdrawing $13 each week.
Let after x weeks your accounts have the same balance.
Hence, We can formulate;
⇒ $22 + $11.50x = $218 - $13x
Solve for x as;
⇒ 22 + 11.50x = 218 - 13x
⇒ 13x + 11.50x = 218 - 22
⇒ 24.50x = 196
⇒ x = 196 / 24.50
⇒ x = 8

Answer:
11,180
Step-by-step explanation:
The usual assumption for organic growth is that it is exponential. Here, the number increased by a factor of 1000/200 = 5 in 8 hours. For t in hours, a model for population might be ...
b = (initial value)·(growth factor)^(t/(period of growth))
b = 200(5^(t/8))
Using t = 20, the predicted population is ...
b = 200(5^(20/8)) = 200·5^2.5 ≈ 11,180
There might be about 11,180 bacteria in 20 hours.
