<PRE><B>Question 308820</B>
anne marie has 52 coins in dimes and quarters, which are worth $6.25. how many of each coin does she have?
-----------------------------
Equations:
Quantity: D + Q = 52 coins
Value:::10D+25Q = 625 cents
-------------------------------------------
Multiply thru Quantity by 10 to get:
10D + 10Q = 520
-----
Subtract that from Value and solve for Q:
15Q = 105
Q = 7 (# of quarters)
----
Since D+Q = 52, D = 45 (# of dimes)
==========================================
