One day, a person went to a horse racing area. instead of counting the number of humans an horses, he conuted 74 heads and 196 legs. how many humans and horses were there? a. 37 humans and 98 horses b. 24 horses and 50 humans c. 31 horses and 74 humans d. 24 humans and 50 horses

Each horse and person has 1 head
we know that people+horses=74
p+h=74
1 person has 2 legs
1 house has 4 legs
p=number of people
h=number of hourses
number of legs=196
4 times h=number of legs if h hourses
2p=number of legs if p people so
196=2p+4h
divide by 2
98=p+2h
multiply first equation by -1
-p-h=-74
add to current equation
p-p+2h-h=98-74
0p+h=24
there were 24 hourses
subsitute
24+p=74
ssubtract 24
50=p
there were 524 horses and 50 people
the answer is B
