Problema Solution

You have exactly $100.00 to spend. You must get 100 animals. The chicks cost $0.10 each. The pigs cost $2.00 each. The sheep cost $5.00 each. You must get some of each animal. How many of each animal can you get?

Answer provided by our tutors

we have three variables and two equations 

Let Pig = p ,sheep = s , chick = c 

AS per total animal equation 

P + S +C = 100 

as per cost equation 

2*P + 5 * S + 0.1 * C = $100 

let number of Chick = 60 

Therefore 

P + S = 100 - 60 = 40 

And 2 P + 5 S = 100 - (60 * 0.1) =  94 

solving these two equation 

we get 

P = 32 , S = 8 , C = 60 

 

pig = 32 , sheep = 8 , chick = 60
