A group of fisherman charted a boat for 300 dollar. Two members of the group were unable to go o the trip and as a consequence, each of the others had pay 12.50 dollars more.How many shares did he sell?
------------
Let original # of sharer's be "x":
-----
Original share price = 300/x dollars
------
New share price = 300/(x-2) dollars
------
Equation:
300/x - 300/(x-2) = 12.50
-------
300(x-2) - 300x = 12.5x(x-2)
-------
12.5x^2 - 25x + 600 = 0
-------
x^2 - 2x + 48 = 0
(x-8)(x+6) = 0
Positive solution:
x = 8 (original # of shares)
