Answer 1

Answer:

The number candy bar packages must be less than or equal to  5 . The maximum number is 5.

Step-by-step explanation:

Let the number of candy bar packages be  n .

6.50  -  5.75

Now we can drop the dollar signs from every number and simplify.

18  -  6.5  -  1.15n   ≥   5.75

11.5  -  1.15n   ≥   5.75

Subtract  11.5  from both sides of the inequality.

-1.15n  ≥  -5.75

Divide both sides by  -1.15  and flip the inequality sign.

n   ≤  5

The number candy bar packages must be less than or equal to  5 . The maximum number is 5.

(I think this is right)
