Hi,
sally has 12 coins consisting of {{{highlight(x)}}}quarters and {{{highlight(12-x)}}}dimes.
Question states*** the value adds to $2.25
Translate into an equation: CENTS makes sense
  25x + 10(12-x) = 225¢
       15x = 105¢
          x = 7, number of quarters.  5 Dimes
and...
{{{25*7 + 10*5 = 225}}}
