Answer:
chickens cost $8
ducks cost $5
Step-by-step explanation:
c= chicken cost
d =duck cost
50c + 30 d = 550
44c + 36d = 532
divide the first equation by 10
5c + 3d = 55
multiply it by -12
-60c -36c = -660
now add the modified first equation to the second equation
-60c -36c = -660
44c + 36d = 532
-------------------------
-16c = -128
divide by -16
c = 8
a chicken costs $8
now lets find d
5c+3d = 55
5*8 + 3d = 55
40 + 3d = 55
subtract 40 from each side
3d = 15
divide by 3
d = 5
