So for this, we will be creating an equation using the exponential formula - which is (a = initial value, b = growth/decay).
Firstly, we know that the original population of the deer is 1,500 so that will be our a value.
Next, we know that the population is growing by 2% annually. With this, we will <em>add</em> 1 and 0.02 (2% in decimal form) since the population is <em>increasing</em>.
- 1 + 0.02 = 1.02
1.02 will be our b variable. Now putting it together, our equation is:
Now that we have our equation set up, plug 4 into the x variable and solve for y as such (Remember to not round until the very end):
<u>After 4 years, the deer population will be 1,624.</u>
Answer:
x = 90
Step-by-step explanation:
- x -
x +
x = - 70
Multiply through by 45 ( the LCM of 9, 45, 5 ) to clear the fractions
- 40x - 4x + 9x = - 3150 , that is
- 35x = - 3150 ( divide both sides by - 35 )
x = 90
