Is this what u want?
Answer: There is 22 possible combinations.
Step-by-step explanation:
%a is equal or greater then 11 and it is odd
count=0;
P=[];
for a=11:2:499
b=a+2;
%assume a and b are prime;
prime=1;
%check if a and b are prime
for k=2:ceil(sqrt(b))
%if a OR b is divisible by k, break
%it is not prime
if mod(a, k)==0 | mod(b, k)==0
prime=0;
break;
end
end
if prime
count=count+1;
P(count, :)=[a b];
end
end
fprintf('There is %d possible combinations.\n', count)
display(P)

Answer:
I think that it is something to do with the atmosphere and the way that the light bounces around it. Here is some information from a website to back this up. "The Short Answer: Gases and particles in Earth's atmosphere scatter sunlight in all directions. Blue light is scattered more than other colors because it travels as shorter, smaller waves."
You can use logic to say right off the bat that you have 2 one dollar bills
if you said you had 7 instead there would be not enough bills to add up to 82
so that means 4 $5 and 6 $10
check you have 12 bills and it adds up to $82
2 $1
4 $5
6 $10
