Michael breeds chickens and ducks. last month, he sold 50 chickens and 30 ducks for $550. this month, he sold 44 chickens and 36 ducks for $532. how much does a chicken cost, and how much does a duck cost?

Respuesta :

n the following step there is a multiplication error: 
50c + 1330/3 - 110/3c = 550 
150c + 1330 - 330c = 1650 
110/3 was multiplied by 3 twice instead of once. It should just be 110 

Continuing onward... 
150c + 1330 - 110c = 1650 
40c = 320 
c = 8
