Final answer:
After adding a 10% tax and a 15% tip to Allam's $15 meal, the total amount he will need to pay is $18.75.
Step-by-step explanation:
The student's question relates to calculating the total cost of a meal including tax and tip. To answer this, we need to apply a few mathematical operations based on percentages. First, let's assume the tax rate is 10% and that Allam wants to leave a 15% tip. Here's how we calculate each part:
- Tax: 10% of $15 = $1.50
- Tip: 15% of $15 = $2.25
- Total additional charges (tax + tip) = $1.50 + $2.25 = $3.75
- Final amount Allam needs to pay: $15 (original meal price) + $3.75 (additional charges) = $18.75
So, with tax and tip included, Allam will pay a total of $18.75 for his meal.
