An investor bought 225 shares of stock, stock A at $50 per share and stock B $75 per share. If $13,750 worth of stock was purchased, how many shares of each kind did the investor buy?
--------
Quantity: f + s = 225 shares
Value: 50f+75s = 13750
--------------------------------
Modify:
2f + 2s = 2*225
2f + 3s = 550
-----
Subtract and solve for "s":
s = 100 (# of $75 shares)
----
Solve for "f":
f = 225 - 100 = 125 (# of $50 shares)
-------------------------------------
