Andrea has $18 to spend. She spent $6.50, including tax, to buy a notebook. She needs to save $5.75, but she wants to buy a snack. If candy bars cost $1.15 per package including tax, what inequality would show the maximum number of packages that Andrea can buy? Solve your inequality by showing your work and steps.

Let the number of candy bar packages be n .

$18 - $6.50 - $1.15n ≥ $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 .
