X = the number of humans and y = the number of horses.
x+y=74
2x+4y=196
Because the number of humans and horses together is 74, and the total number of legs (2 per every human, x, and 4 per every horse, y) is 196. Then, just use elimination to solve.
![-2(x+y=74)\\2x+4y=196\\\\-2x-2y=-148\\2x+4y=196\\\\2y=48\\y=24](https://tex.z-dn.net/?f=-2%28x%2By%3D74%29%5C%5C2x%2B4y%3D196%5C%5C%5C%5C-2x-2y%3D-148%5C%5C2x%2B4y%3D196%5C%5C%5C%5C2y%3D48%5C%5Cy%3D24)
So, now that you have y, you can plug it into the first equation to find x:
![x+y=74\\x+24=74\\x=50](https://tex.z-dn.net/?f=x%2By%3D74%5C%5Cx%2B24%3D74%5C%5Cx%3D50)
So, x = 50 and y = 24, so there are 50 humans and 24 horses.
The correct answer is B.
Answer:

Answer:
$6000
Step-by-step explanation:
accumulated amount = A = PI
A = $6900
Let P = x
6900 - I = x
I = (x)(0.05)(3yrs) = 0.15x
6900 - 0.15x = x
Add
6900 = 1.15x
Divide, solve for x
x = 6000
