Question 1017726
p,n,d,q
pennies, nickels, dimes, quarters


{{{system(d+q=2+n,p=q,p+5n+10d+25q=93)}}}


Using {{{p=q}}}
{{{q+5n+10d+25q=93}}}
{{{5n+10d+26q=93}}}


Using {{{n=d+q-2}}}
{{{5(d+q-2)+10d+26q=93}}}
{{{5d+5q-10+10d+26q=93}}}
{{{15d-10+31q=93}}}
{{{15d+31q=103}}}-----------This seems bad.  Look for any mistakes in the work shown.  Also recheck your original problem description.
