10) A box of floor tiles costs \( \$ 15.85 \). If the total bill before tax is \( \$ 190.20 \), how many boxes of tiles were purchased?

To find out how many boxes of tiles were purchased, you can divide the total bill before tax by the cost per box. So, \( \frac{190.20}{15.85} \) gives approximately 12 boxes. That’s right! You’d need to purchase 12 boxes of those snazzy tiles to hit that total bill amount. Understanding how to break down costs like this can save you money in more than just tile shopping! Next time you’re budgeting for a project, try using this simple formula: Total Cost = Cost per Item × Number of Items. It can help you prevent overspending whether you're buying decor, groceries, or planning a party!
