$16.40 because she bought 2 candies so you will add 1.80 +1.80 or could of times 1.80x2 then subtract $20 for what you get adding or multiplying then that's how you get what she has left.
-4<em>n</em> ≥ 12 ==> <em>n</em> ≤ -3
<em>n</em> + 5 > 2 ==> <em>n</em> > -3
But <em>n</em> cannot be both less than/equal to -3 AND greater than -3, so there are no integers <em>n</em> that satisfy these inequalities.
