Alright, if Victoria's age is x and her neighbor's age is n, then n+4=x as Victoria is 4 years older than her neighbor.
Since their sum is 14 or less, then x+n≤14 (less than or equal to). In addition, as n+4=x (and x-4=n by subtracting 4 from both sides), we can substitute that in to get x-4+x≤14 and 2x-4≤14. Adding 4 to both sides and dividing by 2, we get x≤9
If the prices are multiples of 2, then (excluding $0 or free), then the possible prices are such that they add up to $10.
Possible prices are
