You can put this solution on YOUR website!
Let +x+ = the number of $10 coins
+2x+ = the number of $50 coins
+100%2F5+=+20+ the number of $5 coins
------------------------------------------------
(1) +100+%2B+10x+%2B+2x%2A50+=+4500+
(1) +10x+%2B+100x+=+4400+
(1) +110x+=+4400+
(1) +x+=+40+
------------------------
+10x+=+400+
+100x+=+4000+
------------------------
Janice collected
$100 worth of $5 coins
$400 worth of $10 coins
$4000 worth of $50 coins
