Answer 2

d

Explanation:

D. 24 humans and 50 horses.

We can use a system of equations to solve for the number of horses (x) and number of humans (y):

x + y = 74 (the total number of heads)

y = 196 - 4x (the total number of legs, with each horse having 4 legs)

Substituting the second equation into the first:

x + (196 - 4x) = 74

5x = 122

x = 24.5 (number of horses rounded down to the nearest whole number)

y = 74 - x = 50 (number of humans)
