Answer:
they are different because of the mode sign on the second 's',
which if you are wondering what it stands for,
it represents only the magnitude of the value needed, not its sign,
let the assumed value of s be -5,
for example iin the first case, s < 3
hence s = -5, and it is true for s < 3
OR
if we take the second case, lsl < 3
that would be s = 5 [ not -5], which would not be true for lsl < 3
i hope u understood it,
if any more questions...please ask :)
Add 6.5 to both sides
D=-0.7

Answer:
Yes and she would have $2 left over because all the food costs $91.
Step-by-step explanation:
We should set up an equation so that everything makes sense. A calculator would be wise for this problem, but I am going to lay it out anyhow.
We should convert the mixed numbers to improper fractions to not be confused. 3 1/2 becomes 7/2 or 3.5 and 2 1/3 becomes 7/3.
From your wording, we can assume that the money Mrs. Donnelly has is either greater than or equal to $93.
Thus, we have 12*(7/3) + 18*(7/3) is equal to or greater than 93 (this is an inequality).
The math shows that the food costed 91 and so she only has $2 left.
