I can start with 50 dimes
+.1%2A50+=+5+ $5
---------------------
I'll try 40 dimes and 10 quarters
+.1%2A40+%2B+.25%2A10+=+6.5+ $6.50
--------------------------------
I'll try 42 dimes and 8 quarters
+.1%2A42+%2B+.25%2A8+=+6.2+ $6.20
----------------------------------
I'll try 43 dimes and 7 quarters
+.1%2A43+%2B+.25%2A7+=+6.05+ $6.05
----------------------------------
I'll replace one of the dimes with a nickel
+.1%2A42+%2B+.05%2A1+%2B+.25%2A7+=+6+ $6.00 -OK
================================
Now I'll start with 16 quarters
+.25%2A16+=+4+ $4.00
---------------------------
I'll try 16 quarters and 34 nickels
+.25%2A16+%2B+.05%2A34+=+5.7+ $5.70
-------------------------------
I'll try 17 quarters and 33 nickels
+.25%2A17+%2B+.05%2A33+=+4.25+%2B+1.65+ $5.90
-------------------------------
I'll try 18 quarters and 32 nickels
+.25%2A18+%2B+.05%2A32+=+4.5+%2B+1.6+ $6.10
-------------------------------------
It looks like I need to replace one of the
quarters with a dime and one of the nickels with a dime, so
I'll try 17 quarters, 2 dimes, and 31 nickels
+.25%2A17+%2B+.1%2A2+%2B+.05%2A31+=+4%2C25+%2B+.2+%2B+1.55+ $6.00 -OK
----------------------------------------------------
I'm sure more are possible
