From Wikipedia:

Four Loko contains carbonated water, sugar, and natural and artificial flavoring including FD&C Red 40. The drink is sold at 6%, 7%, 8%, 10%,12%, 13.9% or 14% alcohol by volume (ABV), depending on state regulations, and is packaged in 23.5 oz (695 mL) cans.

14% seems to be the top end, not the bottom end, and not available everywhere at even that strength.

So in some markets Four Loko does break 10% but comes nowhere near 40%.

Now write me a 5 paragraph MLA formatted essay with at least 4 citations on what "showing your work" means to you.
