{{{P+5N+10D+25Q=273}}}
.
.
{{{N=2D}}}
{{{D=N/2}}}
.
.
{{{N=Q+1}}}
{{{Q=N-1}}}
.
.

{{{P=2+2N}}}
Substituting,
{{{P+5N+10D+25Q=273}}}
{{{2+2N+5N+10(N/2)+25(N-1)=273}}}
{{{2N+5N+5N+25N+2-25=273}}}
{{{37N=296}}}
{{{N=8}}}
So then,
{{{P=2+2(8)=2+16=18}}}
{{{D=8/2=4}}}
{{{Q=8-1=7}}}
18 pennies, 8 nickels, 4 dimes and 7 quarters
