## Logic Question – A Bottle of Wine

**ANSWER: **Well, if the total cost is $10.00 and the wine is worth $9.00 more than the bottle, you might be quick to say that the value of the bottle is $1.00. You would be wrong. Let me explain:

Think of it as an algebraic equation where X is the value of the bottle.

Bottle = X

Wine = X + 9 (because it’s worth $9 *more* than the bottle)

X + (X+9) = 10

2X + 9 = 10

2X = 10 – 9 = 1

2X = 1

Ergo: X = 0.5 (50 cents)

So the bottle is worth $0.50 and the wine is worth $9.50.
