GED Math: Calculating Restaurant Tips Using Percent Equations

Understanding the Percent Equation

• 🎯 The problem involves finding a percentage of a number, specifically calculating an 18% tip on a restaurant bill.
• 🔑 The formula used is Part = Base × Rate, where 'Part' is the tip amount, 'Base' is the total bill, and 'Rate' is the percentage as a decimal.

Calculating the Tip Amount

• 💡 To find the tip, the restaurant bill of $56.48 needs to be multiplied by the tip percentage.
• 💰 The tip percentage of 18% must first be converted to a decimal by dividing by 100, resulting in 0.18.
• 📈 Multiplying the bill ($56.48) by the decimal rate (0.18) yields $10.1664.
• 💸 This amount is then rounded to $10.17, which is the recommended tip for the waitress.
