if I understand correctly
neighbors truck = n
your truck = m
m >= n+500
m<= 1/4(4n)
so, if we simplify the second one
m<=n
this isn't possible because the first equation contridicts this statement, so it's no solution?
While I think guest is right, I believe 0 and 1 can also work since they both have 1 as their answer.
