1500. since hes marking it up by 50% then take half of 3000 to get your answer
Hi there!
As you mentioned in the question -- growth:
We plug in the data from the question into the formula to find our answer.
p = initial value = 1,000 people
r = increasing rate = 5% = 0.05
(We've found this number by dividing by 100)
n = amount of years = 5
a = outcome
Therefore the population consists of 1276 people after 5 years.
~ Hope this helps you!
B because the range of variables doesn't matter right now in this equation,Write the formula so you can check it after and the do your variables!!
Exponential Growth
Some real-life events grow in such a way that they can be modeled as an exponential function, given as:
Where C(t) is the future value of the measured variable, Co is its initial value, r is the growth rate and t is the time.
We are given the following data:
Initial amount: Co=40 bacteria
Growth rate: 1 + r = 3
The bacteria triples every 4 days, thus t is the number of periods of 4 days.
Thus the model is:
We can solve the equation
1 + r = 3
And get r = 2. Rewriting the equation:
We are required to find the number of bacteria after 20 days, that is, after 20/4 = 5 periods of 4 days. Substituting:
Calculating:
The colony would have 9,720 bacteria after 20 days
