You can put this solution on YOUR website! Michael has a total of $6.65\$6.65$6.65 in dimes and quarters, and he has 202020 coins total. Which of the following systems of equations can be used to find out how many ddd dimes and qqq quarters he has?
========================
D + Q = 20 (# of coins)
10D + 25Q = 665 (value of coins)
etc
=================
Nothing followed.
------------------------------------
PS If all the coins were quarters,
20*25 = $5.00
--> no solution
