                 dollar per roll     How Many Rolls     MONEY, Dollars
Quarters Rolls    10 each              3n                 10*3n
Dimes Rolls        5 each              2n                  5*2n
Nickels Rolls      2 each               n                   2n
TOTAL                                                      $252

Make the obvious equation and solve for n and the roll counts.
