<PRE><B>Question 1026593</B>
A farmer bought a number of pigs for $252. However, 7 of them died before he could sell the rest at a profit of $9 per pig. His total profit was $126. How many pigs did he originally buy?
--------
# he originally bought:: &quot;x&quot;
Price per pig 252/x
-------------------------------------
After 7 died
# of pigs:: x-7
Profit on the x-7:: 9x-63
----
Equation:
9x-63 = 126
9x = 189
x = 21 (original # of pigs)
