The number of nickels is 5 times the number of dimes. Their value is $1.05. How many coins od each type are there?
-------------------
Equations:
Quantity: n = 5d
Value: 5n + 10d = 105 cents
-------------------------------
Substitute for "n" and solve for "d":
5(5d) + 10d = 105
35d = 105
---
d = 3 (# of dimes)
---
Since n = 5d, n = 15 (# of nickels)
