-------------------------------------------------------------
Value equation: 25c + 30t + 35b = 670 cents
Quantity equation: b = 3c
Quantity equation: c + t + b = 21
---------------------------------------
Rearrange:
25c + 30t + 35b = 670
3c + 0 - b = 0
c + t + b = 21
-----------------------
Use any method you know to get:
c = 4
t = 5
b = 12
