RE: Math mini-contest problem for Day 11 on D.Buzz 😎

Can't sleep even though I am tired.😩

I think @eturnerx-dbuzz is right. Replying for @ecency points. 😊 35 horses and 15 of those horses have riders.

Horses have 1 head each. Riders have 1 head each. At least that seems to be right in my fatigued state.

horses + riders = 50

Horses have 4 feet. Riders have 2 feet. Thankfully @savvyplayer clarified that since that's not true on every planet.

r + h = 50
2r + 4h = 170

2r + 4h =170
-2(r + h) = 2(50)

2h = 70 / 2 = 35 horses a.ka. 35 horse heads with 140 horse feet. 15 rider heads with 30 feet.
