Question 279327
Since I don't have change for  50 cents, I can have
at the most 1 quarter.
I can have any number of dimes, and I still won't have
exact change for $1
If I have 7 or more dimes, I can't have any nickels at all,
since that would give me change for a dollar
And, since I don't have change for a dime, I'm allowed 1 nickel
If I don't have change for a nickel, I'm allowed 4 pennies
--------------------------------------------
The combination that seems to satisfy all these
conditions is
{{{1}}} quarter
{{{9}}} dimes
{{{1*25 + 9*10 = 115}}}
