Answer:
3200
Step-by-step explanation:
Given that:
The initial population of birds 
= 100
The time duration t = 5 years
Growth rate (r) = (Birth - Death) rate
= 2 - 1
= 1 / year
∴
using the discrete-time form:
<span>21,000*5
since it travels 21,000 per hour and there is five hours. it's just simple substitution.
105,000 is the correct answer.</span>

<h3>
The dietitian provide 2.5 numbers of salmon steak, 1 baked egg and 2 acorn squash for the patient. </h3>
Step-by-step explanation:
Let
Number of salmon steak = x
Number of baked eggs =y
and Number of acorn squash =z
Total amount of protein that is provided to the patient =40 x +20 y+3 z
Total amount of carbohydrates that is provided to the patient = 20 x+2y +15z
Total amount of vitamin A that is provided to the patient = x+25 y+ 37z
According to the problem,
40x+20y+3z=126, 20x+2y+15z=82 and x+25y+37z= 101.5
Solving the above equations
we get x= 2.5 ,y= 1 and z=2
So , The dietitian provide 2.5 numbers of salmon steak, 1 baked egg and 2 acorn squash for the patient.
If you crossed multiplied than got an equation than x=6 ( if that's what your looking for)
