You can put this solution on YOUR website!
PRICE      CHICKENS COUNT       COST DOLLARS
  15           x                15x
  30           y                30y
   5           c                 5c
TOTAL         20                200

system%28x%2By%2Bc=20%2C15x%2B30y%2B5c=200%29

Try substitute for c. Look for a solution that x, y, c, are whole numbers.
