Answer :
Final answer:
The correct expression for calculating the total bill after leaving a 22% tip on an $84 meal is 84 + 84(0.22). Mr. and Mrs. Green's dinner would cost $84.96 after adding an 18% tip to their $72 meal.
Explanation:
To calculate the total bill the Starks would pay after leaving a 22% tip on their $84 meal, you need to determine the tip amount and then add it to the original bill. To find the tip, convert the 22% to a decimal by dividing by 100, which gives you 0.22, and then multiply it by the cost of the meal, $84. The expression for this calculation is:
Tip = Meal Cost × Tip Percentage
Tip = $84 × 0.22
This calculation gives you the amount of the tip they would leave. After calculating the tip, add it to the original bill to find the total amount they will leave at the restaurant. The expression that represents the total payment is:
Total = Original Bill + Tip
Total = $84 + ($84 × 0.22)
The correct expression from the given options would be 4) 84 + 84(0.22).
Using the example of Mr. and Mrs. Green's dinner bill: The cost of their meal before tipping was $72. With an 18% tip, the calculation would be $72 + ($72 × 0.18). Convert the percentage to decimal (18% = 0.18), multiply by the meal cost to find the tip, and then add the tip to the original meal cost to find the total cost of their dinner.
The final calculation would be:
$72 + ($72 × 0.18) = $72 + $12.96 = $84.96
Thus, the total cost of dinner for Mr. and Mrs. Green, including tip, would be $84.96.
