Question 760134
There can't be 4 quarters, since that = $1
-----------------
There can't be 3 quarters, since the most number of
coins would then be 3 quarters + 25 pennies, and
that is only 28 coins
-----------------
If there are 2 quarters, the largest number of coins 
is 2 quarters + 50 pennies = 52 coins. If you subtract 
2 pennies, you only have {{{ 2*25 + 48 = 98 }}} cents
