Question 930430
In a western film, the desparado sits at the poker table with a stack of coins worth $50. There are as many silver dollars as there are quarters. Figure out the total number of coins. 
----------------
Equations:
Quantity:: s = q
Value:: 1*s + 0.25q = 50 dollars
------
Substitute for "s" and solve for "q"::
q + 0.25q = 50
1.25q = 50
q = 40 (# of quarters)
Solve for "s":
s = q = 40 (# of silver dollars)
