Question

Fiona has $18 to spend. She spent $4.25, including tax, to buy a notebook. She needs to save $9.75, but she wants to buy a snack. If crackers cost $0.50 per package including tax, what inequality would show the maximum number of packages that Fiona can buy? Solve your inequality by showing your work and steps.

I think the answer is 8 but I don't know how to make an inequality. Please help.

Answer 1

8 packages

Explanation:

First, let's subtract.

#1) Remove the cost of the notebook.

• $18 - $4.25
• $13.75

#2) Remove the amount that needs to be saved.

• $13.75 - $9.75
• $4.00

#3) Make the inequality.

• Let n be the number of packages.
• 0.50n ≤ 4.00
• n ≤ 4.00/0.50
• n ≤ 8
