There are lots of posts explaining this type of clue.

Think of this clue as having a left side (\$4.99 and Lee) and a right side (hamburger and iced tea).

In this case, if \$4.99 is hamburger, then Lee must be iced tea.

If \$4.99 is iced tea, then Lee must be hamburger.

That's the logic being expressed by the clue.

So if we find that Lee cannot be \$6.99, since we know that \$4.99 cannot be \$6.99, then the whole left side cannot be \$6.99.

Said another way: The only way for the left side to have a \$6.99 option is for Lee to be \$6.99.

Now since the right side can only be one of the two options on the left, if the left side can never be \$6.99, then neither of the two options on the right can be \$6.99.

The hint spells this out. It is stating that Lee cannot be \$6.99, so one of the other clues must have provided this piece of the logic. The hint goes on to conclude that since the left side can never be \$6.99, then hamburger cannot be \$6.99. It turns out that iced tea can never be \$6.99 either. So you can actually place two Xs for this hint.
