Question

5) A farmer raises turkeys and pigs. There are 15 animals all together. The farmer

counts 34 legs on these animals. How many of each type of animal does the farmer
have? (See #7 in Notes)
t-turkey
p-Pigs

Answer 1

2 pigs, 13 turkeys

Explanation:

34=2t+4p (equation for legs)

t+p=15 (equation for total # of animals) --> t=15-p

substitution:

34=2(15-p)+4p

p=2

plug back in to other equation

t=15-(2)

t= 13
