Answer= 12. hope this helped. almost 100% sure this is right.
Answer: Brand B is the best unit price
Explanation:
Brand A:
6 = 54$
1 = 54/6
1 = 9$
Brand B:
9 = 63$
1 = 63/9
1 = 7
So brand B is much cheaper
Let a and b be integers and b>a, then we can say:
(b-a)/3=5 now multiply both sides by 3
b-a=15
b=15+a
So there are infinitely many pairs of integers that satisfy the conditions given in the problem. For any value a, b will be 15 units greater.
