I really need help with this problem!

 

While on a walk in the country, you pass a field full of horses and chickens. After a quick count, you determine there are 3232 heads and 9090 feet in the field. How many of each animal are there?

Assuming there are no amputees or mutants with more than one head:

 

c x 2 + h x 4 = 90  feet

 

and

c+h=32   heads

h= 32-c     Substitue this into the first equation

 

2c + 4(32-c) = 90    solve to find   c = 19      the remainder are horses    32-19 = 13 horses

EP i think you misread everything in your equation would be multiplied by 101.

 

so there are 1919 chickens and 1313 horses.

 

HOPE THIS HELPED!

Nah...... there are numerous instances where the questioner's numbers get repeated   9090 is really 90    3232 is actually 32....dont know why it happens, but it does fairly regularly.  cheeky
