NO they are not proportional

Let
x-------> bags of <span>popcorn
</span>y-------> bags of hotdogs
we know that
2.50x+3y=200-------> equation 1
x=2y--------> equation 2
substitute 2 in 1
2.50*[2y]+3y=200--------> 5y+3y=200------> 8y=200-----> y=200/8
y=25
x=2y-----> x=2*25-----> x=50
the answer is
50 bags of popcorn
25 bags of hotdogs<span />
Answer:
613297
Step-by-step explanation:
The equation for exponential decay is y=A(1-r)^t
A=654,000
r (rate)=0.008 (0.8% as a decimal)
t=8 (2009-2000=8)
y=659,000(1-0.008)^8
y=613297.4028
Since you can't have part of a person, round: y=613297
