  Let $0<\lambda\leq1$, $\lambda\notin\left\{\frac24, \frac27, \frac2{10},
\frac2{13}, \ldots\right\}$, be a real and $p$ a prime number, with
$[p,p+\lambda p]$ containing at least two primes. Denote by $f_\lambda(p)$ the
largest integer which cannot be written as a sum of primes from $[p,p+\lambda
p]$. Then \[f_\lambda(p)\sim\left\lfloor2+\frac2\lambda\right\rfloor\cdot
p\text{, as }p\text{ goes to infinity.}\]
  Further a question of Wilf about the 'Money-Changing Problem' has a positive
answer for all semigroups of multiplicity $p$ containing the primes from
$[p,2p]$. In particular, this holds for the semigroup generated by all primes
not less than $p$. The latter special case was already shown in a previous
paper.
