Math Lesson

So Keymaster and I went to Gloria's last night for some much needed drinks. On Mondays, Tuesdays and Wednesdays, Gloria's has Happy Hour prices on their margaritas and sangrias: $2 each. I could not decide between the margarita and the sangria, so I requested a swirl. I was charged $4 dollars for this drink. Outrageous. Simple math tells us that this is an incorrect price.

Here, I will show my proof.

margarita = 2
sangria = 2
x= margarita
y= sangria

z = ½x + ½y
z = 1 + 1
z= 2

Therefore, my drink which compose one half of x and one half of y should have equaled $2. But no, those cheating cheaters at Glorias charged me full price for x and full price for y though I only had half of each. Cheaters!

I would say I would never go back, but that black bean dip is just too good to pass up. But I will not be ordering the sangrita without confirmation of the mathematical inconsistency in their pricing procedures.
