You can put this solution on YOUR website! there are 8 times as many dimes as nickels, and the value of the dimes is $9.00 more than the value of the nickels. how many nickels and dimes are there?
----
quantity: d = 8n
value: 10d = 5n + 900
------
Substitute for "d" and solve for "n":
10(8n) = 5n + 900
75n = 900
n = 12 (# of nickels)
---
Solve for "d":
d = 8n
d = 8*12 = 96 (# of dimes)
