It's 17 right?

3x = 30
x=10
x + 2y = 20
2y=10, y=5
y + 2z = 9
2z=4, z=2
y + ((0.5z)(x)) = ?
5 + (0.5(2)(10)) = 15

fucking brainlets, this is middle school tier algebra, you literally have no excuses if you get this incorrect.

Because it ruins the logical order of the maths operations. You'd end up multiplying the wrong variable otherwise

if not 17, then my phd. in magneto electrodynamics is worthless.

No. That's not what I'm asking. I'm asking why you think that because "PEMDAS" aka the order of operations exists, that in this context it is therefore appropriate to multiply bottles and beers BEFORE adding beers and burgers. Why do you think that's what you're supposed to do here?

Mutts can't count, no surprise, mutts have danish DNA (7%)

I have bad news for you..

yes

congratulations, its 100% worthless
