Final answer:
To calculate an 18% tip for a $25.10 meal, convert 18% to a decimal (0.18) and multiply by the meal cost to get the tip amount ($4.52). Adding the tip to the original cost gives a total of $29.62.
Step-by-step explanation:
If you want to leave an 18% tip for a meal that costs $25.10, you should first convert the percentage to a decimal by dividing it by 100, which gives you 0.18. Then, multiply this decimal by the cost of the meal to find the amount of the tip. $25.10 × 0.18 = $4.518, which we round to $4.52 for convenience.
Next, to find the total amount you will pay, including the tip, you add the amount of the tip to the original cost of the meal. So, $25.10 + $4.52 = $29.62. Therefore, the total cost of your meal including an 18% tip will be $29.62.
