Answer: a is the # of elements in A but NOT B, that is A ONLY
b is the # of elements in B but NOT A, that is B only
N is the # of elements in the INTERSECTION of A and B
a + N = 99
b + N = 25
a + b + N = 123
Subtracting the first two equations: a - b = 74
Subtracting the last two equations: -a = -98
a = 98
So then a - b = 74 and a = 98
98 - b = 74
-b = -24
b = 24
a = 98, b = 24 and a + b + N = 123
98 + 24 + N = 123
122 + N = 123
N = 1
98 are in A only
24 are in B only , which is the answer to the question
1 is in both A and B

Solve:-
Find unit price per pack.
6-Pack:-
2.49 ÷ 6 = <span>0.41
$</span><span>0.41 per can
12-pack:-
3.99 </span>÷ 12 = 0.33
<span>0.33 per can
24-pack:-
5.49 </span>÷ 25 = <span>0.22
</span><span>0.22 per can
</span>
The cheapest is 24-pack, because the unit price for that is the cheapest. After that pack is the 12-pack one because that is cheaper than the 6-pack. and last is the 6-pack. <span />
