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.
