Answer:
yes I can help
Step-by-step explanation:
which one please
Based on the information given the percent of the total cost of the bike has Wu saved is 30%.
Using this formula
Total cost percentage=Amount saved/Cost×100
Where:
Amount saved=$75
Cost =$250
Let plug in the formula
Total cost percentage=$75/$250×100
Total cost percentage=30%
Inconclusion the percent of the total cost of the bike has Wu saved is 30%.

Answer:
It will increase by 24 starfish
Step-by-step explanation:
The population is modeled by the following differential equation:
![\frac{dN}{dt} = rN](https://tex.z-dn.net/?f=%5Cfrac%7BdN%7D%7Bdt%7D%20%3D%20rN)
Which has the following solution:
![N(t) = N(0)e^{rt}](https://tex.z-dn.net/?f=N%28t%29%20%3D%20N%280%29e%5E%7Brt%7D)
In which N(0) is the initial population and r is the growth rate.
A population of 2000 starfish has a yearly per capita population growth rate of 0.012.
This means that ![N(0) = 2000, r = 0.012](https://tex.z-dn.net/?f=N%280%29%20%3D%202000%2C%20r%20%3D%200.012)
By next year, how do you expect population size to have changed?
This is N(1).
![N(t) = N(0)e^{rt}](https://tex.z-dn.net/?f=N%28t%29%20%3D%20N%280%29e%5E%7Brt%7D)
![N(1) = 2000*e^{0.012}](https://tex.z-dn.net/?f=N%281%29%20%3D%202000%2Ae%5E%7B0.012%7D)
![N(1) = 2024](https://tex.z-dn.net/?f=N%281%29%20%3D%202024)
2024 - 2000 = 24
So the correct answer is:
It will increase by 24 starfish
