  1. all this takes is a bit of trial and error
    you clearly need either
    2 pennies or 7 pennies.
    7 pennies is out, since there is no coin worth 80 cents
    so, now you have
    pp + 6 coins making 85 cents
    qqq = 75¢, leaving 5 coins for the other 10¢ -- nope

    ppqq = 52¢, leaving 4 coins for 35¢
    looks like
    ppndddqq
